The Fire Alarm System Project integrates Arduino with temperature and gas sensors to identify potential fire risks. When abnormal temperature or gas levels are detected, the system activates an alarm, ...

This project uses an HC-SR04 ultrasonic sensor to measure how close an object is. A buzzer and LED react depending on the distance, similar to a car parking sensor. < 10 cm → buzzer and LED stay on.

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

The goal of this module is to teach students about the properties of sound and computing distance with an ultrasonic sensor. The program can also be used to measure the relative distance. This module ...

If you have an upcoming long distance move and you're concerned about thieves breaking into your moving truck you can rig up a motion alarm system that will send a text message as well as trigger an ...

Abstract: LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and ...
