Students at the National Institute of Technology in Karnataka, India, are using a Raspberry Pi to bring together air quality readings and make them available on the internet. The students (Richie John, Shishir Sheshadri and Aparna Velampudi, who are studying Electronics and Communication Engineering), and their professor M S Bhat, will distribute sensors which are connected to a network. The network hub will be a Raspberry Pi which will expose the results to the outside world. They have already used the system to study air quality on the NIT-K campus and they hope to encourage others to use the readings and turn it into a fully-fledged system. Story found on Times of India.
