MQ3 Alcohol Gas Detector Alcohol Ethanol Sensor Module for Arduino

  • Sale
  • Regular price Rs. 185.00


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
