The place where I live is nearby an industrial hub. Sometimes I could feel the pollution level increasing. So I decided to install a CO tracker that can track the Carbon Monoxide emission easily. I made it using Particle electron which works with GSM and connects to the cloud to push the data. The data was accessible in the android app. After a month of collecting data, I could see the emission levels. Also, I gave a proposal to the City Corporation for starting a Public addressing system to display the pollution levels in different parts of the city.
