Measuring CO2 Concentration using Arduino and MQ-135 Sensor

This project looks into designing and testing a CO2 sensor using an Arduino UNO. An MQ-135 sensor is tested under different conditions in order to obtain detection limits and measure trends. The literature shows that there is around 400 PPM of carbon dioxide in the atmosphere, the average indoor values range from 35-450 PPM and the maximum acceptable level is around 1000 PPM. The MQ-135 ...
