MQ3 MQ-3 Alcohol Ethanol Sensor Module Breathalyser Gas Checker Breath Detector
A, Size: 32mm X22mm X27mm length X width X height
B, the main chip: the LM393, ZYMQ-3 gas sensor
C Operating voltage: DC 5 Volt
D, features:
1, with the directions of the signal output.
2, two-way signal output (analog output, and TTL level output)
3, TTL output valid signal is low. (When low output signal light, and can be connected directly to the microcontroller)
4, 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage.
5, having a high sensitivity and good selectivity of ethanol vapor.
6, has a long life and reliable stability
7, rapid response and recovery characteristics
F Applications:
For motor vehicle drivers and other non-drinking and operating personnel on-site detection, but also for other places of ethanol vapor detection
