Interfacing MQ135 Gas Sensor with Arduino Electronics ...

20191030· MQ135 is a gas sensor which is sensitive to CO2. The change in CO2 levels changes the resistance of sensor which results in the change in the output of the sensor. The output generated from the sensor is feed to Analog Input to Arduino board ( In my case Arduino Uno). The analog data is taken by ADC of Arduino, according to the voltage levels, it displays CO2 levels in ppm.
