5Pcs HC-SR505 Mini PIR Motion Sensor Module, Infrared Pyroelectric Human Body Detection Sensor, 4.5V–20V Digital Output for arduino for Raspberry Pi MCU Projects

Product Description This module is a compact passive infrared (PIR) motion detection sensor. It detects movement by sensing changes in infrared radiation emitted by warm objects. When motion is detected within the sensing range, the module outputs a digital high-level signal. The module operates within a wide DC voltage range from 4.5V to 20V. It features low static current consumption for energy-efficient operation. The small PCB size allows easy integration into embedded systems and compact enclosures. It can be connected directly to microcontrollers for motion-triggered control applications. Suitable for motion sensing experiments, automation projects, and embedded development systems.
