RCWL-0516 Microwave Radar Sensor Module Human Body Induction Switch Module

Product Description The RCWL-0516 Microwave Radar Sensor Module is a motion detection module that uses Doppler radar technology to detect human body movement and other objects. Unlike traditional PIR sensors, this module can sense motion through thin walls, doors, and plastics, making it highly versatile for home automation, lighting control, security systems, and IoT projects. It provides a digital high/low output when motion is detected, ensuring easy integration with Arduino, ESP32, STM32, and Raspberry Pi. With a detection range of up to 7 meters, wide-angle coverage, and high sensitivity, the RCWL-0516 is a reliable solution for touchless motion-based switching.
