Smartphone Users can Now Detect Air Pollution

A team of computer  scientist at University of California has found that people can monitor the quality of the air if their breathe in real time through their smart phones.

The sensors could be particularly useful to people suffering from chronic conditions, such as asthma, who need to avoid exposure to pollutants. 



CitiSense is the only air-quality monitoring system capable of delivering real-time data to users' cell phones and home computers-at any time. Data from the sensors can also be used to estimate air quality throughout the area where the devices are deployed, providing information to everyone-not just those carrying sensors.
"We want to get more data and better data, which we can provide to the public. We are making the invisible visible," said William Griswold, a computer science professor at the Jacobs School of Engineering at UC San Diego and the lead investigator on the project.

The CitiSense sensors detect ozone, nitrogen dioxide and carbon monoxide, the most common pollutants emitted by cars and trucks.

The user interface displays the sensor's readings on a smart phone by using a color-coded scale for air quality based on the EPA's air quality ratings, from green (good) to purple (hazardous).
