Use an MQ-3 alcohol sensor as a breathalyzer and display the user's BAC.
How to build a device for estimating blood alcohol content from a breath sample. Developed with Zerynth and an ARM board.
It is a tool to monitor the presence of acetone in our breath. It uses gas sensor MQ-135, 1.3inch OLED display, DHT22 & Arduino Uno.
Welcome to another Arduino project video! Today we are going to build an Arduino Breathalyzer. It is a device that senses alcohol in the air
SENSE is a Smart Open Source Breath Analysis Device that can accurately predict the blood alcohol levels in your breath!
A complete project, from the design to the electric scheme, from the PCB to the 3D-printed container.
Let us create a simple breathalyzer with LinkIt One microcontroller.
A customizable breathalyzer that tells you how much you've had to drink
This project will detect any abnormality in the incubator’s conditions, such as low oxygen levels, high temperature, or irregular heartbeat.
This is a project for the course IoT of "La Sapienza" university of Rome. It is a breathalyzer connected to a box containing the car's keys.
Fun hobby project for building entirely open source breathalyzer with MQ-3, Arduino sketch for ANAVI Gas Detector and a lot of LEGO bricks.
This project demonstrates how to implement a low-cost breathalyzer with a GreenPAK™ SLG46140V
