Description Alcohol Gas Sensor MQ-3
This alcohol sensor is suitable for detecting the alcohol concentration in your breath. Similar to a regular breathalyzer. It has high sensitivity and fast response time. The sensor provides an analog resistive output based on alcohol concentration. The driving circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC.
Free breakout
This is a simple breakout board for the MQ-3, MQ-4, MQ-6, MQ-7, and MQ-8 gas sensors. The Gas Sensor Breakout allows you to use any of the oversized, oddly spaced pins on any MQ gas sensor product . This is very handy to have on hand when detecting multiple types of gases.
All you need is VCC to 5V, GND and a resistor to an ADC, that's it!
