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!

Motion detection is an essential part of security systems and PIR sensor is one of the most commonly used sensor for trigging the alarms when motion is detected. This sensor can detect human/animal ...

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.

PIR-Motion-Detector-Sensor-with-Arduino This Project detects motion through PIR sensor, then the signal will give buzzer sound through Arduino. The project is based on the Arduino Avr Atmega328p ...

Motion Detector with Arduino (PIR + LED + Buzzer) This project uses an Arduino board with a PIR motion sensor to detect movement. When motion is detected, an LED lights up and a buzzer sounds. It's ...

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list.

Motion sensor alarms are readily available in the market, but these are expensive. Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security ...

Security Alarm This article is about making an intruder alarm using Arduino and PIR sensor. When the PIR sensor will detect an intruder, it will send a signal to Arduino and the Arduino will sound an ...

Motion detectors vary: PIR detects heat changes, microwave sensors use wave reflection. Best options: SimpliSafe, ADT, Vivint. Installation tips included.

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.
