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!

Even though Attiny85 is fitting here, I opted for Digispark just because of its plethora of features like USB programming interface, on-board voltage regulator, and Arduino IDE compatibility. The code ...

A number of technologies are available to design automatic door openers like PIR sensors, Radar sensors, Laser sensors, Infrared sensors, etc. In this arduino based project, we have tried to replicate ...

PIR Sensor Burglar Alarm with Arduino Uno This project implements a simple burglar alarm system using a Passive Infrared (PIR) sensor and an Arduino Uno. When motion is detected by the PIR sensor, the ...

Utilizando um Arduino, três LEDs, um buzzer e um sensor PIR (Passive Infrared), criamos um sistema de alarme simples que detecta movimentações no perímetro da loja. Quando o sensor PIR detecta ...

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 salt based ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.
