Gas Sensor (MQ3) Alcohol Vapor
The Gas Sensor module is useful for gas leakage detecting(in home and industry). The MQ3 sensor can detect alcohol vapor with adjustable sensitivity via the board's potentiometer.
The detector on the base can be switched with different sensors to detect specific target gases.
- Detects Alcohol vapour at 0.04-4mg/L Alcohol
- Stable performance, long life, low cost
- Fast response
- Wide detection range
- Simple drive circuit
