MQ-3 Gas Sensor Module Breath Alcohol-Ethanol Detection

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.
