Module cảm biến khí ga MQ-2

Product information:

MQ-2 uses SnO2 compound with low conductivity in clean air, when flammable gas exists, the sensor will increase conductivity higher, the higher the flammable concentration, the higher the conductivity of SnO2 will The higher and the corresponding is converted into electrical signal level. The MQ-2 is a highly sensitive gas sensor for LPG, Propane and Hydrogen, methane (CH4) and other flammable vapors, at a low cost and suitable for many different applications.

The sensor outputs both signal types: Analog and Digital, which can adjust the sensitivity of the sensor by fine-tuning rheostat.

Power used: 5VDC

Current: 150mA
