Tracking Air Pollution with the Internet of Things

On the outer-wall of the Internet Education and Research Laboratory (intERLab) at the Asian Institute of Technology (AIT) in Pathum Thani, Thailand, an inverted pink-colored lunchbox attracts observers’ attention. Mounted on the wall is a box with a wire coming out. But a closer look reveals that this is no ordinary lunchbox but one with a full menu of sensors.

This array of sensors can measure PM1, PM2, PM10, temperature, humidity, carbon dioxide, and carbon monoxide, among others. Small, compact, and functional, this is one component in the vast array of the Internet-of-Things (IoT) devices that promise to revolutionize the measurement of atmospheric pollution.
