Datasheet Summary
MQ-2 Semiconductor Sensor for bustible Gas
Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the target bustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
MQ-2 gas sensor has high sensitity to LPG, Propane and Hydrogen, also could be used to Methane and other bustible steam, it is with low cost and suitable for different application.
Character
- Good sensitivity to bustible gas in wide range
- High sensitivity to LPG, Propane and Hydrogen
- Long life and low cost
-...
