Sensor for iPhone and Android will determine the quality of air

American scientists have developed a sensor that is able to analyze the quality of the ambient air and to transmit information to mobile devices. Atmospheric monitoring in real time relevant to people living in metropolitan areas.

A device called CitiSense can provide iPhone and Android smartphones on the status of the environment. The sensor detects the level of ozone, nitrogen dioxide and carbon monoxide - the most common pollutants emitted by cars.

Mobile application that must be installed on your smartphone, displays indications CitiSense with color scale, where green means no pollution, and purple - high content of harmful substances.

To date, the sensor has been tested. The experiment showed that users can not only get information about the level of pollution of the territory on which they are located, but also to adjust their route depending on the sensor performance.

Right now, the device is too large to be embedded in smart phones, but over time it will be possible, scientists say.

Americans big thick fingers could not buy iPhone?

As it turned out, the consultants in commercial networks of mobile operators in the U.S. have been instructed to advise customers not to buy the iPhone, and select Android smartphones, or Windows Phone. The thing is too large subsidies from the cellular phone companies to Apple, who do not benefit providers at the end of the year.

iPhone 4 with two-year contract is free. Apparently, this situation does not suit the operators, as it came to the point of absurdity. A visitor to the salon Sprint could not get the coveted iPhone 4, as the seller assured him that he is too fat fingers for "apple" communicator. The consultant tried hard to prove that the Apple-smartphone is not the best choice. Buyers offer to buy Samsung Galaxy S III, as iPhone - «a piece of shit."

When an employee's third-largest operator in the U.S. realized that the client does not intend to abandon the free iPhone 4, then used his final argument. He said that the buyer was "big thick fingers, and he wanted a smartphone with a large screen."

It is quite natural that the visitor did not appreciate the aspirations of the seller and left the room, left without a cell phone.
