Microwave Radar Sensor Module RCWL-0516

The RCWL-0516 Microwave Radar Sensor Module is an advanced motion detection solution utilizing Doppler radar technology for accurate and reliable human presence detection. Unlike traditional PIR sensors, this module can detect movement through walls, glass, and thin barriers, making it ideal for smart home automation, security systems, and lighting control applications.

This compact sensor operates on a wide voltage range and features impressive detection capabilities with minimal power consumption. The module uses microwave frequencies to detect even subtle movements, triggering a 3.3V output signal that can be easily interfaced with Arduino, Raspberry Pi, and other microcontrollers. Perfect for automatic lighting systems, burglar alarms, industrial automation, and IoT projects.

The RCWL-0516 offers superior performance in various environmental conditions and doesn’t require direct line-of-sight to detect motion. Its 360-degree detection pattern and adjustable sensitivity make it versatile for both indoor and outdoor applications. Easy to integrate and highly reliable, this sensor module is an essential component for modern electronics enthusiasts and professionals.
