Description:

This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC.



Size: 32 *22* 27mm
Main chip: LM393, ZYMQ - 3 gas sensors
Working voltage: DC 5V
Features:
1, With a signal output instructions.
2, two-way signal output (TTL level output and analog output)
3, TTL output signal for low level effectively.(when the low output electric signal lights at ordinary times, 
can be directly by single chip microcomputer)
4, analog 0 - 5V voltage, the higher the concentration, the higher the voltage.
5, to ethanol steam has a high sensitivity and good selectivity.
In June and has long service life and reliable stability.
7, rapid response recovery features.
Application:
Used in motor vehicles and other no drunken drivers homework personnel on-site testing, 
also used in other places of ethanol vapor detection.
