Description:
MQ-3, Alcohol Sensor Module:This alcohol sensor is suitable for detecting alcohol concentration in your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. Indication of the signal output. Dual signal output (analog output and ttl level output). Ttl output signal is low. (When low output signal light and can be connected directly to the microcontroller). 0 ~ 5v analog output voltage, the higher the concentration, the higher the voltage. Mainly used for testing alcohol concentration in your breath. Has a long life and reliable stability. Fast response and recovery characteristics. Technical parameters: Size: 32x22x27mm, main chip: Lm393, zymq-3 gas sensor, operating voltage: Dc 5v, input voltage: Dc5v, power: 150ma, do output: 0.1v/5v, ao output: 0.1-0.3a.
