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!

Deba168's system uses two Arduinos, an RF transmitter, a motion sensor, and a few other parts to piece it all together. When the motion sensor detects movement, it buzzes the other Arduino.

There’s a huge market for 433 MHz alarm system hardware out there, from PIR motion detectors to door and window sensors. If you want to put them to work, all you need is a receiver, a network ...

Using motion detectors and an Arduino you can trigger lights, ... Here is the Arduino code for the Parallax sensor. int motion_1 = 2; ... PIR Pin “Alarm” connects to Arduino Digital 2.

All you need is an Arduino, a motion sensor, a few wires and headers, and the code provided at the site below. Hit the link to see step-by-step instructions on how to put it together.

arduino gsm security alarm. Working of the system is very simple and self-explanatory. When input power is applied to the system, the system goes into standby mode. However, when the terminals of ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so w… ...
