MQ4 Methane Gas Sensor : Pinout, Interfacing with Arduino ...

Sep 11, 2020· MQ4 Methane Sensor Overview. At the heart of the MQ4 is a heater and electrochemical sensor. When the target gas enters the membrane and reaches the sensor, it undergoes a redox reaction which creates current. This current is stronger for sensors at specific gases. In the case of the MQ4, it’s more sensitive to methane, butane and propane.

Interfacing MQ4 Gas sensor with evive STEMpedia

RS is the resistance of the sensor that changes depending on the concentration of gas. R0 is the resistance of the sensor at a known concentration without the presence of other gases, or in the fresh air. Calculation RS = [(Vin x RL) / Vout] RL. Vin is 5V in our case. RL is 10 kOhm; Vout is the analog voltage reading from the sensor
