MQ4 Methane Gas Sensor Robotpark

MQ4 Methane Gas Sensor detects the concentration of methane gas in the air and ouputs its reading as an analog voltage. The concentration sensing range of 300 ppm to 10,000 ppm is suitable for leak detection. For example, the sensor could detect if someone left a gas stove on but not lit.

arduino uno Sensing concentration of methane with MQ4 ...

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.
