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!

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 , ...

English: Code to control a home alarm system with Arduino Uno using a sensor connected to pin 11 and a buzzer on pin 8. When the sensor detects presence (HIGH state), the buzzer emits a sound with ...

A new alarm system is now being developed to provide early detection of possible fire occurrences in the forest. Built with a smoke sensor and a 3G network connection, prototype units of the ...

The TEMT6000 is a cheap and small analog light sensor. The sensor typically comes on a breakout with only GND, VCC and SIGNAL pins. It is not a calibrated sensor however the signal is very useful for ...

Essentially, it is another safety initiative that gives a visual warning of a biker braking, with LEDs tucking up the end of the handlebars. It is based on an 3-axis accelerometer board, provided by ...

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 ...
