2016 New Alcohol Ethanol Sensor Breath Gas Ethanol MQ-3 MQ3 For Arduino 51

Description: Size: approx. 32 x 22 x 27mm Main : LM393, ZYMQ-3 gas detector Working Voltage: 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. For motor vehicles and prohibition drunken drivers homework personnel on-site testing, also used in places of ethanol . is . Package Included:

1 xGas Sensor Module
