Super Phone/Device that can smell chemicals in air.

You might know dog that sniff but recently scientists have developed a phone that can sniff the chemicals in surrounding air. When a chemical is sensed, the application  in this phone warns the user about the chemical in the air.

US Homeland Security’s Science and Technology Directorate has developed the ‘Cell-All’ in which they can equip cell phones with a sensor capable of detecting deadly chemicals in the surrounding atmosphere Ingenious Technology right?.
The chip is really affordable at less than a dollar is embedded in a mobile phone which is programmed either alert the mobile carrier to the presence of toxic chemicals in the surrounding air or a central station that can monitor alerts in an area are being received.

“Our goal is to create a lightweight, cost-effective, power-efficient solution,” said Stephen Dennis, Cell-All’s programme manager.

How would this wizardry work? Just as antivirus software bides its time in the background and springs to life when it spies suspicious activity, so Cell-All would regularly sniff the surrounding air for certain volatile chemical compounds, say the scientists.

When a threat is sensed, an alert ensues in one of two ways. For personal safety issues such as a chlorine gas leak, a warning is sounded; the user can choose a vibration, noise, text message or phone call, according to the scientists.
For catastrophes such as a sarin gas attack, details, including time, location and the compound, are phoned home to an emergency operations center. While the first warning is beamed to individuals, the second warning works best with crowds. And that’s where the genius of Cell-All lies in crowd sourcing human safety, they say.
Because the data are delivered digitally, Cell-All reduces the chance of human error. And by activating alerts from many people at once, Cell-All cleverly avoids the long-standing problem of false positives.
Those who worry about privacy issues can rest assured: Cell-All will operate only on an opt-in basis and transmit data anonymously.
“Privacy is as important as technology. After all, for Cell-All to succeed, people must be comfortable enough to turn it on in the first place,” Dennis said. PTI
