  • This module is made using Alcohol Gas Sensor MQ3.
  • It is a low cost semiconductor sensor which 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.
  • It’s 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.
  • This module provides both digital and analog outputs.
  • Threshold level for digital output can be easily adjusted using the preset on the board.
  • MQ3 alcohol sensor module can be easily interfaced with Micro-controllers, Arduino Boards, Raspberry Pi etc.
  • Operating Voltage : 5V ±0.1 
  • Current Consumption : 150mA
  • Digital Output: TTL digital quantity 0 and 1 (0.1 and 5V).
  • Analog Output: 0.1~0.3V.
  • Concentration : 0.05 mg/L ~ 10 mg/L Alcohol
  • Operation Temperature : -10°C ~ 70°C
