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 ...

Abstract: In recent years, with the increasingly serious problem of environmental pollution, the demand for real-time monitoring and early warning systems in homes and industrial places has been ...

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Alarm systems are complicated affairs. However, if you’re just looking to catch a sandwich thief at work or a cat spilling over all you water bottles, then Make shows you how to build an alarm system ...

This project demonstrates a basic fire alarm system using an Arduino UNO, a gas sensor (MQ-2), and a temperature sensor (LM35). The system continuously monitors the environment for smoke/gas and high ...

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 ...
