Wearable Air Quality Monitor Helps Avoid Pollution Hot Spots
UC Berkeley students bring us 'Clarity' to inspire action on climate change
As manufacturing industries continue to grow around the world, air quality has remained a major concern. In fact, the World Health Organization calls it the worst single environmental health risk and says reducing air pollution could save millions in lives. Passionate entrepreneurs are busy finding opportunities to help solve these problems.
One team of UC Berkeley students have developed a small wearable device called Clarity to measure air pollutants including particulate matter 2.5, volatile organic compounds, nitrogen dioxide and ammonia. Clarity uses sensors that operate as pollution detectors. If you can imagine shining a light on a ball which reflects the light, that is essentially what is happening inside the sensor. Only it’s the reflection of light by the particles that allows it to measure the number of particles in the air.
