Arduino DIY CO2 PPM Meter
In this video, we use the MQ135 gas sensor to measure the concentration of carbon dioxide in the air. We know that the average CO2 level is 400ppm, so by doing a little math and a little stats we can form a curve to calculate the CO2 PPM for any given reading of the sensor. We output this data to an OLED display in both text and as a bar graph ...
