Brief description:

1、 Dimensions: 32mm x22mm x27mm L x W x H
2、 Main chips: LM393, zymq-3 gas sensor
3、 Working voltage: DC 5 volts
4、 Features:
1. With signal output indication.
2. Dual signal output (analog output and TTL level output)
3. TTL output valid signal is low level（ When the output level is low, the signal light is on, which can be directly connected to the single chip microcomputer.)
4. Analog output voltage is 0 ~ 5V, the higher the concentration, the higher the voltage.
5. It has high sensitivity and good selectivity for ethanol vapor.
6. It has long service life and reliable stability
7. Fast response recovery features
5、 Application:
It is used for the on-site inspection of motor vehicle drivers and other operators who are strictly prohibited from drinking, and for the detection of ethanol vapor in other places
