DFRobot Gravity Digital Infrared Motion Sensor for Arduino - 5V, 7m Range, 110° Angle
The DFRobot Gravity Digital Infrared Motion Sensor is a low-power PIR sensor module compatible with 5V Arduino and other microcontroller systems. It provides a digital output signal upon detecting infrared heat changes within a 110° angle and up to 7 meters, ideal for security and automation projects.
Features
- Digital PIR motion sensor with 5V DC operation and 50μA standby current.
- Wide 110° detection angle and up to 7-meter sensing range for area coverage.
- Simple digital output (High/Low) triggers on motion, compatible with Arduino digital pins.
- Compact 28mm x 36mm PCB design with Gravity interface for plug-and-play connectivity.
- Includes a digital sensor cable for immediate integration into prototyping systems.

This sensor utilizes a passive infrared (PIR) element to detect changes in thermal radiation emitted by moving objects, such as humans or animals. Upon power-up, it captures a baseline snapshot of the environment; any subsequent infrared variation within its field of view triggers a logic-low output on its alarm pin.
The module is designed for seamless integration with the DFRobot Gravity ecosystem and standard 5V logic microcontrollers like Arduino Uno. Its low quiescent current makes it suitable for battery-powered or always-on security and lighting automation applications.
