In Brief

CitiSense is a system that lets you check air quality conditions in the palm of your hand.

Developed by computer scientists at the University of California, San Diego, CitiSense may soon allow you to receive real-time air pollution data for your location on your smart phone.

CitiSense is a portable, box-like sensor that can be deployed to provide local air quality information to everyone within range of the sensor, not just those carrying it. The device provides feedback on things like ozone, nitrogen dioxide, and carbon monoxide levels – the most common pollutants present in vehicle exhaust.
