MQ3 Alcohol Gas Sensor Module
For motor vehicle drivers and other non-drink operations of on-site inspection, but also for other places of ethanol vapor detection, detection of alcohol range: detection range of 10 ~ 1000ppm.
- Size: approx. 32 x 22 x 27mm
- Main chip: LM393, ZYMQ-3 gas detector
- Working Voltage: DC 5V
- With signal output instructions.
- Two-way signal output (TTL level output and analog output).
- TTL output effectively signal for low level(when the output low level signal lights, can directly connected microcomputer).
- Analog output 0 ~ 5v voltage, the higher the concentration, the higher the voltage.
- Has a high sensitivity and good selectivity.
- Has long service life and reliable stability.
- Rapid response recovery features.
- For motor vehicles and other prohibition drunken drivers homework personnel on-site testing, also used in other places of ethanol vapor detection.
