MQ4 Gas Sensor-SE-1010-D

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
long lifespan
low cost
simple drive circuit &etc.
Applications:-
It is widely used in domestic gas leakage alarm
industrial flammable gas alarm and portable gas detector
