RCWL0516 Microwave Radar Motion Sensor Module The RCWL0516 is a versatile microwave radar sensor module designed for accurate motion detection across a wide range of applications. Offering sensitivity and a large detection angle, it delivers reliable performance in environments where precise motion sensing is essential. Key Features: sensitivity for detecting subtle movements Long detection range for enhanced coverage Wide operating voltage range for flexible power options Large sensing angle for broad area monitoring reliability for consistent operation over time Capable of detecting through nonmetallic barriers such as glass, drywall, ceilings, and floors Functionality and Performance: This module can detect moving objects, including those without heat signatures, as long as they have sufficient density and volume. By operating on microwave radar principles, it offers detection through a variety of materials, providing an advantage over traditional infrared sensors. The detection range may vary depending on the amount and type of shielding between the sensor and the moving target. Compatibility: Works with Arduino, NodeMCU, Wemos, and similar microcontroller platforms Suitable for integration into custom electronics projects and prototyping Can detect humans, small animals such as cats and rats, and even moving water Applications: 1. Home automation systems – for controlling lights based on motion, even through walls or doors 2. Security and alarm systems – capable of detecting intrusions without requiring lineofsight 3. Smart device integration – as a trigger in IoT projects where motionbased activation is needed Additional Considerations: The RCWL0516 is sensitive; power supply filtering may be recommended in certain setups to ensure stability. Documentation and tutorials are available on request for ease of integration into your project. This microwave radar sensor module combines strong realworld detection capability with easy compatibility, making it an ideal choice for motiondriven systems across residential, commercial, and experimental applications.
