Description

MQ-3 Gas Sensor Module detects the presence and amount of alcohol / ethanol present in the air. MQ-3 module is suitable for detecting Alcohol, Benzine, CH4, Hexane, LPG, CO. Sensitive material of MQ-3 gas sensor is SnO2, which with lower conductivity in clean air. When the target alcohol gas exist, the sensor’s conductivity is more higher along with the gas concentration rising. MQ-3 gas sensor has high sensitivity to Alcohol, and has good resistance to disturb of gasoline, smoke and vapor.

Specifications :

  • Power requirements: 5 VDC @ ~165 mA (heater on) / ~60 mA (heater off)
  • Current Consumption: 150mA
  • DO output: TTL digital 0 and 1 ( 0.1 and 5V)
  • AO output: 0.1- 0.3 V (relative to pollution), the maximum concentration of a voltage of about 4V
  • Detecting Concentration: 0.05-10mg/L Alcohol
  • Interface: 1 TTL compatible input (HSW), 1 TTL compatible output (ALR)
