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.
