Beschreibung
Descriptions:
1.The gas-sensitive material used by MQ-2 gas sensor is SnO2, which has low conductivity in clean air.
2.When there is combustible gas, the conductivity of gas-sensitive material will increase as the gas concentration increasing.
3.Can be used in homes and factories for leakage monitoring device to detect gas, butane, propane,methane,smoke,etc.
