What Is A Humidity Sensor And How Is It Useful?

By A Noton

Humidity sensors are used in homes as part of the HVAC (Heating, Ventilation, and Air Conditioning,) as well as in office buildings and industry. They are used in places that are affected by high and low humidity that requires a set constant humidity to be maintained. A humidity sensor, also referred to as a hygrometer, is a device that measures the humidity in the air. The humidity sensor monitors the electrical changes in relation to the quantity of humidity in the air. It is used to control such machines as air conditioners, humidifiers, and dehumidifiers by adjusting to the changes in the level of humidity in the air.

Humidity sensors are beneficial for people who suffer from health conditions that are aggravated by high humidity. As well, a person with allergies or asthma can use a humidity sensor because low humidity can aggravate these conditions and too much humidity can cause the growth of fungus, bacteria, mold, and mildew which can also aggravate these conditions. They are also useful for people with wine cellars who want to maintain a constant temperature and humidity so wine does not spoil. As well, humidity sensors are useful for storage of valuable items such as antiques which can be damaged if exposed to moisture. The sensor mechanism of the humidity sensor detects the electrostatic changes in the air as the humidity in the air around it changes.

The benefit of humiduty sensors in industry are they allow for accurate measurements and recording of humidity data. The data loggers can be used for real-time monitoring and sends an alert if there are sudden changes. Once the sensor picks up the changes, the measurement is then converted into humidity readings and recorded in a data logger. The changes in voltage are converted into digital readings showing the amount of moisture in the air. There is the choice of using a couple of data loggers in one application or numerous data loggers for monitoring broadly dispersed locations. It is useful for mapping and validation, and data logging and recording, for reports.

Three types of sensor technologies are Resistive, Capacitive, and Thermal Conductivity sensing. Resistive sensors are useful when using them in remote locations. Capacitive sensors are beneficial for wide RH range and condensation tolerance. Thermal conductivity sensors are beneficial in corrosive environments that have high temperatures. The type of sensor used will depend on the type of environment. Commercial and office buildings often have humidity sensors in their HVAC systems, which assists in keeping the air safe and healthy to breathe. Humidity sensors also have industrial uses for the manufacturing of materials that are sensitive to moisture. As well, humidity sensors are used for collecting data for weather stations and ocean research where humidity has to be measured and recorded for a period of time to evaluate patterns and forecast weather.

Advancements in technology have made it possible to control humidity for a variety of reasons such as to maintain healthy indoor air, protect items from moisture exposure, and for different research applications. There are a number of companies online that specialize in providing quality humidity sensors that are highly accurate and resistant to damage from physical and chemical contaminants.

Eight year old Victoria Stafford of Ontario missing since Wednesday

Tuesday, April 14, 2009

Victoria Stafford, eight years old, was sighted leaving her Woodstock, Ontario school on Wednesday afternoon with an unknown woman caught on video camera. She has not been seen since.

Victoria (Tori) attended grade 3 at Oliver Stephens Public School, and the video is from the College Avenue secondary school as Victoria and the unidentified woman walked along Fyfe Avenue.

“I’ve had a lot of problems come up in my life and stuff like that, and I haven’t always been there for my kids, but this is my baby girl and it’s absolutely hurting now,” her father Robert Stafford said, “It’s killing me, [I want to] let her know that I love her and I’ll see her soon. One way or another I’ll see her soon.”

Police teams from Oxford, Waterloo and London have assembled together with rescue dogs and trained search and rescue personnel to find the child.

Police have called the search a criminal investigation, but have not yet issued an Amber alert as there has been no report of an abduction.

150 volunteers joined search efforts and to pass out flyers on the 10th. Police say they have no need of more volunteers at this time, however they would appreciate any tips or calls from anyone who may have seen either Victoria or the woman.

The unidentified woman seen in the video is described as between 19 and 25 years old with straight long black hair. She weighs about 120 to 125 pounds and was wearing a white coat and black jeans in the video. Victoria was wearing a green shirt with a black pleated skirt. She was wearing black and white shoes and carried a purple and pink Bratz purse. She had on a black Hannah Montana jacket which had a white fur lined hood.

“I think what’s happening with members of the public is an expression of their emotions, their concern for this child. And I think that’s good in terms of the willingness of this community to step up,” said Michael Harding, Mayor of Woodstock.

Volunteers are making and handing out purple ribbons, Tori’s favourite colour. A candlelight vigil will be held in the evening on Easter Sunday.

How To Take Clean Drinking Water}

How to Take Clean Drinking Water

by

Berkeysomers32

If you are like most Americans, you are aware that water supplies are not as dependable as we would like. Over 2100 contaminants have been discovered in drinking water thus far. Our water source may be free of some of these, but who knows which are still present?

Many reading this will have acted on these warnings and stopped drinking faucet or well water. For you only filtered water is worthy of your family or yourself. That means you are either purchasing bottled water, or that you have bought a water filter and are purifying it yourself.

The problem is, when you go on vacation or on a camping trip, you don’t want to trust the water supplies available to have the same healthy water you enjoy at home. If you are purchasing bottled water, then you’ll take along a case or two. This option will probably provide you with safe water, but it is the most expensive. Over eight billion gallons of filtered water are sold annually at prices at times exceeding gasoline. Bottled water may not be as pure is the label indicates but it would be fine for camping. However, keep in mind that if you discard the plastic bottles you use on your vacation, you only add to the environmental problem of plastics that could sit in land fills for centuries.

[youtube]http://www.youtube.com/watch?v=mgg8JqUJEsY[/youtube]

Perhaps you have purchased a gravity feed water filter. If so, you will save money over bottled water and will not have multiple bottles to discard or recycle. If the unit is portable, take it with you on vacation so that you can guarantee the water you drink away is as good as that you drink at home.

What if you either have a built in filter, or don’t have room to take your gravity fed water filter with you? In that case, a little planning ahead would still provide the same water you drink at home. You filter extra water and store it to take with you.

But in what should you store and transport it? The water is clean but you certainly don’t want to jeopardize your family’s health by storing it in unsafe containers. Perhaps you have heard the recent plastics warnings. The PET bottles (made of polyethylene terephthalate) used by most bottled water companies, are safe enough as long as they are not reused. However, if you store water in them where it is warm, plastics can contaminate the water over time.

What about the hard plastic bottles for sports drinks or water coolers? The National Institutes of Health recently showed that bisphenol, used to make these bottles, may cause neurological problems in developing babies. They have yet to discover the long range effects on adults. That may be a bit risky to store and transport water in those containers too.

Few choices remain. You want the purified water from home but cant bring the filter. If you take filtered water from home and store it in unsafe containers, you defeat your purpose. The solution to this dilemma is to filter extra water at home and store it in glass containers. This would include bottles, jars, and glass lined thermoses.

This choice solves several problems. We will have the clean water we want without the problem of discarded bottles. Further we have the peace of mind that the bottle will not contaminate the water. The bottles can be washed and reused without danger to you or your family.

Are you unsure of the water quality where you go camping? If so, you could solve that problem with a portable water filter.

20 tons of cocaine seized by US Coast Guard

Tuesday, April 24, 2007

The United States Coast Guard (USCG) has seized 20 tons or nearly 40,000 pounds of cocaine with a street value of over US$500 million in what authorities call one of the largest cocaine busts in history.

Three busts in total were made in a period of nearly one month. The first on February 19, off the coast of Mexico, March 18 off the coast of Panama and on March 25, also off the coast of Panama.

In the first bust on February 19, “the Ecuadorian-flagged fishing vessel Don Juan K was approached in the Pacific Ocean February 19 off the coast of Mexico while allegedly offloading cocaine into “go-fast” (cigarette-style boat) boats. The fishing vessel’s crew apparently set fire to Don Juan K in an attempt to destroy the evidence and flee in the go-fasts. The USCGC Sherman stopped the go-fasts and recovered about 900 pounds of cocaine as Don Juan K sank. The 14 crew members are being processed for further legal action,” said a statement on the USCG’s website.

The second bust on March 18 yielded nearly 40,000 pounds of cocaine.

“The 330-foot Panamanian-flagged motor vessel Gatun was interdicted in the Pacific Ocean Mar. 18 off the coast of Panama while heading north toward the United States. Sherman’s crew stopped and boarded the vessel and found 765 bales of cocaine weighing approximately 38,000 pounds in two shipping containers. Gatun was escorted back to Panama and its 14 crew members processed for further legal action,” added the statement.

In the third bust on March 25, at least 2,000 pounds of cocaine was seized, also from a ship off Panama’s coast.

“[The] Sherman’s crew stopped and boarded a small stateless go-fast in the Pacific Ocean Mar. 25 off the coast of Panama following a short chase, in which, the go-fast attempted to flee at a high rate of speed. Approximately 2,000 pounds of cocaine was found aboard the go-fast and its four crew members were processed for further legal action,” said the statement.

Several agencies both in the U.S. and in other countries in Central and South America and will continue to investigate the extent of the drug ring.

“The Coast Guard works in close coordination with Joint Interagency Task Force South, U.S. Attorney’s office, Panama Express South, DEA, FBI, Bureau of Immigration and Customs Enforcement, and Customs and Border Protection, as well as the Departments of Justice, State and Homeland Security on counter drug operations in the Pacific Ocean near Central and South America. These drug smuggling routes are some of the most active, yielding roughly 70 percent of the cocaine seized annually by the Coast Guard,” added the statement.

68 pieces of luggage found behind Texas pet store

Wednesday, December 27, 2006

At least 68 different pieces of luggage has been found behind a pet store inside a garbage dumpster in Houston, Texas. The luggage came from several different international flights and authorities do not know how they got there or if the contents of the luggage have been stolen.

“We’re going to be investigating and the authorities are going to be investigating,” said spokeswoman for Continental Airlines, Mary Clark. All luggage was handed over to Continental Airlines.

The luggage is reported to have been sifted through, and most pieces have come from all over the world. The luggage is reported to have come from Bush Intercontinental Airport. Some pieces of the luggage have name tags and Clark states that “we’re trying to reach whoever we need to let them know the bags are there.”

Officers with the Houston Police Department are in charge of the investigation. The luggage was found by individuals who own the pet store.

The FBI has stated that the bags do not pose any danger.

At least four dead and hundreds of homes destroyed after week of wildfires rage throughout Texas

Friday, September 9, 2011

Parts of Texas have been scorched by sweeping wildfires this week. Officials state that a wildfire which swept much of central Texas this week destroyed at least 1,400 homes and forced about 5,000 people to evacuate to safety. An official with the Texas Forestry Services told news sources on Thursday that much of that fire has been contained.

Officials have speculated that this fire alone has destroyed more homes than any other wildfire on record in the state. Officials are welcoming dropping temperatures, stating this will increase their ability to fight the fires effectively. A converted DC-10 aircraft was recently made available to fire authorities, but cannot be used until Friday as workers still need to time to prepare on-board equipment.

One of the two fatalities in the central part of the state has been identified as Michael Troy Farr, 49, who died at his home. Earlier in the week, a woman and her infant died in a related blaze that quickly engulfed their home located near the city of Gladewater, located in the eastern part of the state. On Thursday, officials warned that East Texas has become the center of wildfire activity in the state.

At least 170 wildfires have ravaged much of the state over the past week. On Tuesday, a thick haze of smoke enveloped the city of Tyler for several hours, forcing school officials to cancel all outdoor sports activities. Since late 2010 the overall devastation of wildfires in the state is estimated to cost at least US$216 million (£136 million, 157.5 million) in firefighting expenses. The state’s Lieutenant Governor, David Dewhurst, who is the acting governor in Governor Perry’s absence, indicated he will ask the federal government to declare Texas a major disaster area. President Obama has also promised to provide needed assistance to local officials.

Last British volume car manufacturer closes down

Friday, April 15, 2005

The last British-owned volume car manufacturer, MG Rover, has closed down, with the loss of 5,000 jobs.

International accounting firm PriceWaterhouseCooper was brought in last week to put the company into administration. Today PwC announced that MG Rover’s only hope, the Chinese car company SAIC, had no interest in buying the ailing firm. With no further source of revenue, PwC has closed the company’s factory in Longbridge, Birmingham and has laid off 5,000 workers.

Some 1,000 workers will continue for a while to complete the remaining cars left on the production line.

The BBC reported PwC joint administrator Tony Lomas as saying “We’ll explore what we would describe as the break-up of the business, we will carry on with the interested parties who want to talk about pieces of the business.”. PwC said around 70 offers for various parts of the company had been made but no serious offers of money made.

Recent efforts to save the company had been centered on convincing SAIC (Shanghai Automotive Industry Corp.) to buy the company as a going concern, but the Chinese company stated it would only buy the company if it’s financial position could be guaranteed to be secure for at least two years. The British government could not make such a commitment due to European Union trade and competition rules.

The SAIC company did buy the designs for the 75 and 25 models and for the K-Series engines for £67m.

The Rover car company has a long but troubled history. It was formed in 1968 after a series of mergers of existing car manufacturers, and was nationalized in 1975 after it ran into financial difficulties. In 1979 a long-running deal to collaborate on developing new vehicles was established with the Japanese company Honda. In 1988 the company was privatized and was bought by British Aerospace. In 1994 British Aerospace sold the business to BMW, who then sold the Land Rover brand to Ford and finally sold the company in 2000 for just £10, retaining the well-known Mini brand for themselves. The MG Rover company was run by a private group until its collapse.

MG Rover has not launched a new model since the 75 was introduced in 1998 during the period of ownership by BMW. Their next newest model was the 25, originally launched as the 200 series some ten years ago. Rover also produced the 45, which dates from 1990, and the ZF sports car first launched in 1995. Sales of Rover cars accounted for just 3% of the UK car market in 2004.

Tony Blair announced a £150 million support package for the recently unemployed workers of the MG Rover plants, though it has been claimed that his generous offer may be more as a result of the nearby marginal seats in the upcoming elections than compassion on his part.

London court jails man after Dark Web ricin sting

Friday, September 18, 2015

Mr Justice Saunders today imprisoned a man for eight years at the Old Bailey in London after an FBI sting in which he tried to buy ricin on the Dark Web.

Everyone needs to know that the possession of a chemical weapon is extremely serious and long prison sentences will follow

Mohammed Ali, 31, from Liverpool, was convicted at trial of attempting to possess a chemical weapon. He told the jury he was “curious” about the Dark Web, which is a largely hidden and difficult to police section of the Internet. Ali said he didn’t realise he had done anything illegal.

Ali was prosecuted under the Chemical Weapons Act 1996 after sending an undercover agent a message reading “Hi, would you be able to make me some ricin and send it to the UK?” He bought 500mg, which has the potential to kill about 1,400, but was sent a dummy package. Counter-terror police in the UK liaised with the FBI.

The powder, which Ali paid for in BitCoin, was actually harmless. Hidden inside a toy car, the package was treated with markers and his face glowed under ultraviolet light, indicating he had handled it. The judge said today there was “real risk” involved.

Ali told his trial he had discovered drugs and guns for sale. Computer analysis showed he had looked up ricin and other poisons; he said he went for ricin simply because it had appeared in Breaking Bad. He also searched for small animals after being advised to test it on a rodent; a to-do list on his computer included “paid ricin guy” and “get pet to murder”.

Mr Justice Saunders said the case called for “a deterrent sentence”, which “will appear harsh to the defendant and his family.” “Everyone needs to know that the possession of a chemical weapon is extremely serious and long prison sentences will follow.”

Public Speaking Courses It Is All About You (But Maybe Not In The Way You Think)}

Submitted by: Daniel Kingsley

Some people assume that public speaking is mostly about your audience – giving them what they want and what they require, and they’re partially right. Others say that public speaking is all about your relationship with your audience – really being present with them and really being accessible to them, because if your audience feel in rapport with you, they will be more willing to pay attention to what you have to say. Check below to find useful information on overcoming your fears with Public Speaking Courses.

Livingston Taylor (who teaches a course in relational performance at Berklee College of music) gets closer to the truth when he says: “This is a great game of Simon Says”. The audience have employed you to take control. They want to get into your reality. If you are still, they’re still. If you are tense, they’re tense. If you’re at ease, they’re. If they trust you, they will put themselves in your hands”.

This is greatly put and very true – the way you show up as a speaker, your inner state, does essentially impact the way an audience experience a speech and how they relate to you. But even this isn’t really the end of the story. Because what if you are not calm, relaxed and comfortable? What if you are pressured and frustrated? What then? And this shows you that the most essential element of the jigsaw is still missing. This is the element about your inner game.

[youtube]http://www.youtube.com/watch?v=i6fIc3o_STE[/youtube]

We often say of someone (including a speaker or performer) who looks naturally confident that they are “comfortable in their own skin”. This phrase holds the solution to understanding the inner game of public speaking. Where’s the person? They’re in their own skin – their focus is inside of them. This means that at the moment of providing a speech or presentation to an audience, they aren’t thinking about how they’re showing up from their audience’s perspective. They’re inside their own skin feeling their own feelings.

So, what to do when you catch yourself mentally outside your body, imagining stuff about what your audience are thinking about you? Easy. Drop it. Choose to imagine that your audience are supporting you unless you have any hard evidence to the opposite. You’ll generally be right.

The most important thing to notice about emotions is that they’re like waves. They arise (sometimes from nowhere, at times in response to a situation), they lurk around for a while, and then they subside. It is inevitable that a wave will rise, and it is just as unavoidable that it will fall. And like the waves in the ocean you cannot prevent emotions. But you can learn to surf. Surfing feelings is actually like surfing waves, rather than addressing them as an issue you treat them with fascination. As opposed to waiting for them to disappear, you discover how to ride them.
