PIR Sensor Module – Motion Detection for Arduino, Security, and Automation Projects
The PIR Sensor Module detects motion by sensing changes in infrared radiation, making it ideal for security systems, smart lighting, and automation. It’s easy to use, low-power, and highly compatible with Arduino, Raspberry Pi, and microcontroller platforms.
 
Key Features:
Motion Detection
Uses passive infrared (PIR) technology to detect human or animal movement in its field of view.
Digital Output
Outputs HIGH when motion is detected, LOW when idle—easy to interface with microcontrollers.
Adjustable Sensitivity & Delay
Onboard potentiometers allow fine-tuning of detection range and output hold time.
Low Power Operation
Consumes minimal current, making it ideal for battery-powered devices.
Onboard Indicator
LED turns on when motion is detected for visual confirmation.
 
Applications:
Intruder detection and home security
Automatic lighting systems
Motion-activated alarms
Smart home automation
Energy-saving electronics
DIY electronics and robotics
