Meeting Room Air Quality Monitoring

Hackergrant Project Proposal

Project Champion: Steve Dalton

Ever been in a meeting room with too many people in it and poor air-conditioning and felt like you couldn’t think or could do with a nap. You were probably suffering from the elevated CO2 levels in the room. A similar thing can happen in your car with you have the air-con on reflow for a long time and there is a theory that this could responsible for some car accidents involving tiredness.

My project is a simple CO2 monitoring system using Arduino and various networking modes to push data to the cloud and give alerts when levels are high. I want to try a few different options.
