MQ-3 Alcohol Sensor Module Ethanol Breathalyzer

Ethanol alcohol sensor module.
MQ gas sensor uses a small indoor heater with an electrochemical sensor.
When the alcohol molecules in the air comply with the electrode the ethanol "changes" into acetic acid and then more current is produced.
MQ-3 Alcohol Sensor Module Ethanol Breathalyzer features:
- Main chip: alcohol sensor MQ-3 and comparator LM393
- Working voltage: 5V
- Current: 150mA
- Digital output: TTL 0/1
- Analog output: analog voltage sensing value
- Detection concentration:
- 0.05mg/L - 10mg/L
- Quick response features:
- Adjustable sensitivity with the potentiometer
- Size: 32mm x 20mmx 18mm
