Air Quality Sensor | MySensors Forum

Aug 03, 2014· epierre The MQ135 sensor, for example, has an internal heater inside, which consumes 800mW max. This disqualifies the sensor for battery powered applications as the batteries would run out very fast. A sensor module like the MQ135 has an analog output voltage, which you can feed to an analog input of your Arduino.
