Description
In this project, we are Interfacing a Alcohol Sensor with Arduino. Here we have designed a Arduino Shield PCB for Arduino Uno. **Arduino Alcohol Detector **will detect the alcohol level in breath and by using some calculations in code we can calculate the alcohol level in breath or blood and can trigger some alarm. You can find here the complete [Arduino Alcohol Detector project tutorial](https://circuitdigest.com/microcontroller-projects/arduino-alcohol-detector-circuit-board).
