20150509· VRL = map (sensorValue, 0, 1023, 0, 5000); Once you have the voltage, you can compute the resistance of the sensor using the formula. Rs= (Vc/VRL1)×RL. with Vc the circuit voltage (5V), VRL the voltage over the load resistor, and RL the resistance of the load resistor in Ohms. The tricky part is to convert this to a concentration in ppm CH4.

20200911· 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.
