MQ-3 Alcohol Gas Sensor Ethanol Detection

MQ3 Alcohol Gas Sensor detects the concentrations of alcohol gas in the air and ouputs its reading as an analog voltage. The sensor can measure concentrations of 0.04mg/L to 4mg/L. The concentration sensing range is suitable for breathalyzers. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.

Specifications:
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

Applications:
For motor vehicles and other prohibition drunken drivers homework personnel on-site testing, also used in other places of ethanol vapor detection

Package Includes:
1 x MQ-3 Sensor
