The temperature sensor (U2) is used to monitor the ambient temperature. The Arduino can analyze temperature changes in conjunction with flame sensor data to enhance the accuracy of fire detection.

In this project, we will build Gas Leak Detection & Alarm System using MQ2 Gas Sensor and Arduino UNO Board. The MQ2 sensor is a versatile gas sensor capable of detecting a wide range of gases as well ...

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 gas sensors ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

Arduino based Fire Alarm – Circuit and Working Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...

This Arduino based IR reflectance sensor can be easily modified and adapted for various practical applications, including line-following robots and proximity or edge detection.

The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...
