The Microwave Radar Sensor Module (RCWL-0516) is an advanced motion detection sensor that operates on Doppler radar technology. Unlike traditional PIR sensors, this module detects motion by emitting electromagnetic waves and sensing changes in wave reflection, making it more sensitive and reliable in detecting motion through thin walls, glass, or other obstacles. It is ideal for smart lighting, security systems, and automation projects where precise motion detection is critical.
The RCWL-0516 operates in the 3.2 to 3.7 GHz frequency range and provides a detection range of up to 7 meters. It features a wide operating voltage of 4V to 28V, making it versatile for a variety of power supply configurations. The module also has a built-in regulator and output pin for easy integration with microcontrollers, making it suitable for DIY electronics projects, smart homes, and industrial automation.
