Brief description
1、 Size: 32mm X22mm X27mm Length X Width X Height
2、 Main chips: LM393, ZYMQ-3 gas sensor
3、 Working voltage: 5 volts DC
Characteristics
1. Has signal output indication.
2. Dual signal output (analog output and TTL level output)
3. TTL outputs a valid signal at a low level. When the signal light is on when the output is low, it can be directly connected to a microcontroller
4. Analog output voltage of 0-5V, the higher the concentration, the higher the voltage.
5. It has high sensitivity and good selectivity towards ethanol vapor.
6. Long term service life and reliable stability
7. Quick response and recovery features
Application
Used for on-site inspection of motor vehicle drivers and other personnel strictly prohibited from working under the influence of alcohol, as well as for detecting ethanol vapor in other places.
