Keyestudio PIR Motion Sensor for Arduino

The Keyestudio PIR Motion Sensor is a compact and highly reliable infrared sensor designed to detect movement from people or animals. It is perfect for students, makers, and hobbyists looking to integrate motion-activated triggers into their Arduino projects.

Integrated digital sensor design

Unlike conventional pyroelectric infrared sensors that require complex peripheral circuits, this module uses an integrated digital body sensor. This advanced design ensures a smaller footprint, higher reliability, and simpler integration with your microcontroller.

Ultra-low power consumption

Operating with a working current of just 15uA, this motion sensor is highly efficient and ideal for battery-powered projects. It supports a standard input voltage range of 3.3V to 5V, with a maximum limit of 6V.

Wide detection range

The sensor features a wide 100-degree detection angle and can sense movement from up to 7 metres away. When motion is detected, it outputs a high switching signal of 3V for approximately 2.3 to 3 seconds before returning to 0V.

Onboard LED and compact size

An onboard indicator LED illuminates when the sensor outputs a high signal, making troubleshooting and testing straightforward. Measuring just 30 by 20mm and weighing only 4g, it easily fits into tight project enclosures.
