WebIn this video you will learn how to create an entirely open source breathalyzer with MQ-3 analog sensor module, mini I2C OLED display (SSD1306), an Arduino sketch for the open source hardware ANAVI Gas Detector and a lot of LEGO bricks.. MQ-3 is a low-cost analog sensor module for detecting alcohol. WebHere we are using an array of six LEDs and a 128×64 LCD to display the alcohol level. The presence of alcohol is sensed by an MQ-3 alcohol sensor and then analyzed by an Arduino board. We are using Arduino UNO in this project, but any model can do the job. Three Green LEDs represent that alcohol level is OK and within the safe limit.
