Alcohol Gas Sensor - MQ-3
We have ✅ 12 available of the SF-SEN-08880 in our Sydney warehouse.
This alcohol sensor is suitable for detecting alcohol concentration on 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. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC.
Please review the datasheet for conversions to ppm then Wikipedia.org for BAC.
