MQ-3 Alcohol Gas SensorThis MQ 3 Alcohol gas sensor detects the concentration of alcohol gas in the air and produces an analogue voltage reading. Breathalyzers can detect concentrations ranging from 0. 04 mg L to 4 mg L. The sensor operates in temperatures ranging from 10 to 50C and draws less than 150 mA at 5 V. The heater creates the necessary working conditions for sensitive components. The enveloped MQ 3 has six pins, four of which are used to fetch signals and the
