Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. In this DIY session, we are going to build a Smoke Detector Circuit which not only ...

Nowadays, sensors play a major role in the safety and security of many different apartments, homes and offices by detecting smoke, fire, or gas and providing an alarm to the concerned person. That is ...

This project uses an MQ2 gas sensor, relay module (for motor or exhaust fan), buzzer, and LEDs to create a complete gas leakage detection and alert system using Arduino. When gas concentration crosses ...

Abstract: The application of sensors in smart homes using Arduino to control equipment such as lights, fans, alarms, and so on. Sensors used in Arduino include LDR, Ultrasonic, DHT11, and MQ2. LDR is ...

This project is a safety monitoring system designed to detect hazardous gas leaks using an MQ2 gas sensor interfaced with an Arduino UNO. The MQ2 sensor detects gases such as LPG, methane (CH₄), ...
