Flammable Gas Sensor MQ-4

Profile:

Sensitive material of MQ-4 gas sensor is SnO2, which with lower conductivity in clean air. When the target flammable gas exist, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.

MQ-4 gas sensor has high sensitivity to methane, also has anti-interference to alcohol and other gases.

Features:

It has good sensitivity to methane in wide range, and has advantages such as long lifespan, low cost and simple drive circuit &etc.

Main Applications:

It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector.
