SG03 - Alcohol Gas Sensor (MQ-3)
This xCHIP is equipped to detect smoke and alcohol vapor, much like a common breathalyzer. It has high sensitivity and a fast response time. Sensor provides an analog resistive output based on alcohol concentration.
- High sensitivity to alcohol and small sensitivity to Benzine.
- Fast response and High sensitivity.
- Stable and long life.
- Simple drive circuit.
- Based on the MQ-3 From HANWEI ELETRONICS CO.LTD
