MQ2 General Combustible Gas Sensor


SKU : ABES00175, Category : Sensors
Usually Delivered in 6-7 business days.

Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensors conductivity is more higher along with the gas concentration rising. Please use simple electronic circuit, Convert change of conductivity to correspond output signal of gas concentration. MQ-2 gas sensor has high sensitivity to LPG, i-butane, propane, methane, alcohol, Hydrogen, smoke. The sensor could be used to detect different combustible gas especially Methane, it is with low cost and suitable for different application.
