The Arduino Compatible MQ3 Alcohol Sensing Alarm System Project Kit by Hands On STEM Labs is designed for educational and experimental use. It detects the presence of alcohol vapors in the air using the MQ3 sensor and displays the readings in real-time on a 16x2 LCD screen.
When alcohol is detected above a set limit, the buzzer and LED indicators activate as an alarm system. The Arduino UNO board comes pre-programmed and ready to use, with a pendrive containing the source code, diagrams, and required software for reprogramming or experimentation.
This project is ideal for engineering students, DIY enthusiasts, and research learners who want hands-on experience with sensor-based Arduino systems.
