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!

This is a basic motion-activated automatic door system using Arduino, designed for scenarios like smart entrances or contactless access control. Here's a quick breakdown of how it works and what it ...

The Automatic Door Opener System, employing a PIR or IR Sensor with Arduino, detects individuals in close proximity and automatically opens/closes doors, a technology commonly seen in malls and ...

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 ...

The system here uses a cheap Arduino board, a few sensors, and a magnetic contact switch. It’s then hooked into the Adafruit IO and connected to IFTTT, so you can set up alerts in any way you like.

Abstract: In this paper, the Arduino based Intruder Detection System employing Rochelle Salt and Pyro-electric or Passive infrared (PIR) Sensor has been proposed. The proposed system employs Rochelle ...
