MQ-3 Gas Sensor Module Breath Alcohol-Ethanol Detection

Dual signal output (analog output, and TTL level output)

TTL output valid signal is low, can be connected directly to the microcontroller

0 ~ 5V analog output voltage, the higher the concentration the higher the voltage

The gas, natural gas, city gas, smoke better sensitivity

Has a high sensitivity and good selectivity to ethanol vapor

Has a long life and reliable stability

Rapid response recovery characteristics

Size: 35mm X20mm X20mm/1.37*0.78*0.78″

Input Voltage: DC5V

Power(Current): 150mA

DO Output: 0.1, 5V

AO Output: 0.1-0.3V

Detectable Concentration: 0.04-4mg/L

Application: For motor vehicle drivers and other non-drinking workers on-site inspection, but also for other places of ethanol vapor detection, detection of alcohol range

Package includes:

1 x Module.
