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!

Basically, the PIR motion sensor measures infrared light from objects in its field of view. So, it can detect motion based on changes in infrared light in the environment. It is ideal to detect if a ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor.

Components used in this project: 1x Arduino 101 3x Jumper wire 1x PIR sensor 1x LED light 1x USB cable Background: Arduino 101 is a microcontroller which can take in inputs and produce an output. In ...

In this video tutorial, we will learn how a PIR Sensor works and how to use it with the Arduino Development Board for detecting motion.

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 ...

Working of Dog Barking Security using Arduino Make the connections as per the circuit diagram and upload the code to Arduino Nano. When powered, the PIR sensor detects the IR rays emitted from the ...

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 ...

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.
