This article is about making an intruder alarm using Arduino and PIR sensor ... will be detected by the PIR sensor, it will send a signal to the microcontroller. The microcontroller will then switch ...

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 ideal for simple security systems or motion-based ...

To begin explaining how a basic sensor works, we'll use this rather nice diagram The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens ...

Detecting motions or movements has always been important in most projects. With the help of the PIR Sensor it has become very easy to detect human/animal movements. In this project we will learn how ...

We have already used a PIR sensor for motion detection ... to turn off the detecting function at night if necessary. Wire up the Arduino to the RCWL-0516, and LED as shown in the diagram. The V IN and ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor. When the PIR sensor no longer detects someone in range, it sends a notification over serial ...

Today I am sharing the Proteus simulation of my project, in which I have shown the working of three sensors with a single Arduino. These include a PIR sensor (digital), flame ... with the help of any ...

Get close enough to this raven and you’ll set off the PIR sensor, which triggers ... 12-volt power LED. This bird’s brain is an Arduino Nano, which is protected from the 12V supply with ...
