Smartphone Could Help Detect Air Pollution

"The method we have developed is not only more cost-effective, it also works better than the sensors currently used to detect this dangerous gas."

People could soon be using their smartphones to combat a deadly form of air pollution, thanks to a new low-cost method of detecting nitrogen dioxide (NO2), a significant air pollutant, says a study.
