MQ-3 Alcohol Sensor Detection Module

MQ-3 Alcohol Ethanol Sensor Module Alcohol Gas Detector

Size: 32mm X22mm X22mm length * width * height 

The main chip: LM393, MQ-3 gas sensor 

Operating voltage: DC3-5V

Features: 

1. Signal output instructions; 
2. Dual signal output (analog output, and TTL level output); 
3. TTL output valid signal is low, can be connected directly to the microcontroller; 
4. 0 ~ 5V analog output voltage, the higher the concentration the higher the voltage; 
5. Has a high sensitivity and good selectivity to ethanol vapor; 
6. Has a long life and reliable stability; 
7. Rapid response recovery characteristics;

Applications: 

For motor vehicle drivers and other non-drinking and operating personnel on-site testing, also used in other places of ethanol vapor detection, detection of alcohol: detection range of 10 to 1000ppm

Package:

1pcs MQ-3 Alcohol Ethanol Sensor Module Alcohol Gas Detector
