Air Monitor

Utilising a MH-Z19B CO2 sersor, CSS811 TVOC sensor and a ESP32 micro controller this monitor displays a real time graphs.

It also has a companion Bluetooth app that connects to the Air Monitor to receive live updates of the values as well as a 24 hour graph of the CO2 concentration.

I designed and printed the case, as well as programming the micro-controller firmware plus the Android app.
