Overview

The PIR（Passive Infrared）motion sensor is a passive infrared sensing module that detects changes in infrared radiation caused by the movement of

humans or animals. When motion is detected within the sensing area, the module outputs a HIGH voltage signal. Otherwise, it maintains a LOW voltage.

Features

• Passive infrared sensing: does not emit any

signals, making it energy-efficient and stable

• Built-in digital output, easy to connect with controller

• Detection range: up to 7 meters, sensing angle: approx. 100 degrees

• Suitable for applications like automatic lighting, security systems, and smart home devices

Application

• Automatic door control systems

• Indoor automatic lighting switches

• Motion detection in smart home systems

• Intrusion detection in security systems
