Methane CNG Gas Sensor - MQ-4
Detects Methane gas concentrations anywhere from 200ppm to 10000ppm
If you have any questions on this product please feel free to contact us.
*Disclaimer: The images are merely illustrative.
This is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ-4 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 drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.
Note: Easy connection to an ADC using this breakout board!
