MQ-135 Gas Sensor Pinout, Features, Alternatives ...

2018-02-27· MQ135 is available as a module or as just the sensor alone. If you are trying to only detect (not measuring PPM) the presence of a gas then you can buy it as a module since it comes with an op-amp comparator and a digital output pin. But if you planning to measure the PPM of a gas it is recommend buying the sensor alone without module. Where to use MQ-135 Gas sensor. The MQ-135 …

Measuring CO2 Concentration using Arduino and MQ-135 Sensor

The experiment apparatus would be a packed bed reactor with chemicals producing carbon dioxide. 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 ...
