Air Quality/Fire detection using the Helium ... - Parley Labs

Jul 08, 2020· We will be using the MQ-135 Air quality sensor. It can detect NH3,NOx, alcohol, Benzene, smoke,CO2 ,etc. Doing a quick test by burning a paper towel near the sensor, we can see that Carbon Monoxide (CO) has the highest concentration of detection (as expected), so we’ll use that to monitor for smoke. We’ll start our project off by setting an ...
