The MQ3 Gas Sensor module detects gas leakage in home and industry.
The MQ3 Gas Sensor can detect Alcohol, Benzine, Methane, Hexane, LPG, CO. It can detect the presence of alcohol gases at concentrations from 0.05 mg/L to 10 mg/L
The sensitive material used for this sensor is SnO2, whose conductivity is lower in clean air.
Its conductivity increases as the concentration of alcohol gases increases. It has high sensitivity to alcohol and has a good resistance to disturbances due to smoke, vapor and gasoline.
- High sensitivity and fast response
- Wide detecting scope
- stable and Long life
- Simple drive circuit
- Analog and Digital Outputs
