Description

This gas sensor detects the presence of methane (CNG) gas at concentrations from 300 ppm to 10,000 ppm, a range suitable for detecting gas leaks. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.

MQ-4 gas sensor sensitive material used in clean air conductivity is lower tin dioxide (SnO2).
When the sensor is present in the environment in which the combustible gas,
the sensor’s conductivity increases with the concentration of combustible gases in air increases.
Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal.
MQ-4 methane gas sensor for high sensitivity, propane, butane and has a good sensitivity.
The sensor can detect a variety of flammable gases, especially natural gas,
is a low-cost sensors for a variety of applications.
