CNSensors

This is a simpletouse compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ4 can detect natural gas concentrations anywhere from 200 to 10000ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance.

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. The sensor can operate at temperatures from 10 to 50°C and consumes less than 150 mA at 5 V. Please read the MQ4 datasheet (161k pdf) for more information about the sensor.

11/9/2020· 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.

The MQ4 is attached to an ADC121C 12Bit Analog to Digital converter, which is capable to connect up to 9 gas sensors per I2C port using just two address jumpers (making full use of the floating address system). The MQ4 can sense methane or natural gas air concentration levels between 200 to …

9/5/2015· 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.
