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 Arduino-based burglar detection alarm uses a PIR sensor to detect motion. When movement is sensed, an LED lights up and a piezo buzzer sounds an alert. Ideal for security applications, this sy ...

Intruder Alarm System using PIR Sensor This project demonstrates how to build an Intruder Alarm System using an HC-SR501 PIR sensor, Arduino Uno, a 5V relay, and a buzzer. The system detects motion ...

In this project we will learn how to interface Arduino with PIR sensor and design an arduino based motion detector project with circuit diagram and code.

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

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 ...

Once you get the alarm set up, it’ll sense movement near the Arduino, snap a picture, then send it over to you using If This Then That. All you’ll need is an Arduino Yún, PIR sensor, a USB ...

Since criminality is rising in the 21st century, people want to secure their property and belongings. So, everyone in this situation needs a secure system with cutting-edge technology. Therefore, a ...

Passive Infrared Sensor (PIR) is very useful module, used to build many kinds of Security Alarm Systems and Motion Detectors. It is called passive because it receives infrared, not emits. Basically ...
