Beijing is a city known for having poor air quality, and now design students Xiaowei Wang and Deren Guler have joined forces to create a community initiative, called the Float project, involving the use of pollution-sensing kites. The Float project aims to have the residents of Beijing come together to build the kites and use them to measure and monitor the air quality around the city.
The kites will be built with Arduino pollution-sensing modules and LED lights, says Wired. The modules sense particles and pollutants, such as carbon monoxide. Depending on the air's pollution level, the LED lights on the kite will change colors from green to yellow to red. So far, the Float project has completed a round of funding on Kickstarter and its first kite workshop for Beijing residents will be held July 28.
