PIR Motion Sensor Module

The Whadda UK PIR Motion Sensor Module is a highly versatile electronic component designed for detecting movement within a specified area. Utilising passive infrared (PIR) technology, it senses changes in infrared radiation to detect whether an object has moved into or out of its sensing range, making it an ideal choice for automation, security, and interactive projects.

This module offers a generous maximum detection range of up to 7 metres and a wide 120-degree detection angle, providing excellent coverage. It features adjustable sensitivity and delay settings, allowing you to fine-tune its response to motion. The delay time is adjustable from a short 3 seconds up to 200 seconds, offering great flexibility for different applications. The module operates on a low 5V DC supply, making it compatible with popular development boards like Arduino and Raspberry Pi. It provides a simple digital output signal: 3V (high) when motion is detected and 0V (low) when no motion is present. For easy integration, it features a standard 3-pin male header for connection, with pins clearly labelled as GND, VCC, and OUT.

With its compact dimensions (33mm wide x 43mm high x 15mm deep) and light weight of just 20 grams, this sensor can be easily incorporated into a wide variety of projects, from compact prototypes to permanent installations. Its straightforward interface and reliable performance make it a favourite among hobbyists, students, and electronics enthusiasts looking to add motion-sensing capabilities to their creations.
