Product Description

Description:
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.
Color is shown as pictures.
Package Included:

3 x Gas Sensor Module
