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!

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 ...

The traditional single sensor alarm system has been difficult to meet the requirements of multiple pollutants detection at the same time, so this research proposes a multi-sensor integrated ...

As photons (light) land on the detector, the resistance will decrease. The more light is we will have a lower resistance. By reading different values from the sensor, we can detect if is it light , ...
