Motion Sensors - PIR

Passive infrared (PIR) motion sensors detect ambient infrared radiation changes caused by movement within their field of view, making them the industry standard for human presence detection. Whether you are designing automated indoor lighting with standard HC-SR501 modules, building security alarm systems, or integrating occupancy triggers into your IoT network, our collection provides reliable sensing, adjustable sensitivity ranges, and seamless microcontroller compatibility for all your automation projects.
