Smart phones as air pollution detectors

Smart phones as air pollution detectors
Researchers at RMIT University, Australia have developed a low-cost nitrogen dioxide (NO2) sensor for detecting NO2, which is a significant air pollutant. These sensors when incorporated with smart phones could help in detecting harmful levels of the gas present in the environment. They can function as handheld, personalised, highly selective, sensitive and reliable monitoring system by physically absorbing NO2 gas molecules onto flakes of tin disulphide. Researchers believe that this effective sensing system incorporated into smart phones with their wide public access might help in combating air pollution in a better way than the sensors that are in current use.
