RCWL0516 — Radar Microwave Induction Motion Sensor Module What it does Detects moving objects using radar microwave induction technology for reliable motion sensing. Designed for human presence detection and security applications such as lighting control and antitheft alarms. Key benefits (why you need it) Reliable motion detection: Radarbased sensing reduces missed detections and works in lowlight conditions where optical sensors fail. Wide compatibility: Operates on a broad DC supply range (4.0 V to 28.0 V), making it easy to integrate with many lighting drivers, battery systems, and control circuits. Strong coverage and sensitivity: sensitivity, long induction distance, and a large detection angle help cover larger areas with fewer sensors. Lower maintenance and better uptime: reliability reduces false triggers and the need for frequent adjustment or replacement. Main features and performance Function: Radar microwave induction detection of moving objects (motion/presence sensing). Operating voltage: 4.0 V to 28.0 V DC. Detection performance: sensitivity, extended induction distance, and a large induction (detection) angle for broadarea coverage. Reliability: Designed for stable, longterm operation in lighting and security systems. Practical applications (use scenarios) Automatic indoor lighting: Trigger corridor, stairwell, closet, or restroom lighting only when people are present to save energy and extend lamp life. Security and alarm systems: Integrate into antitheft alarms and perimeter detection to detect intruders or unexpected movement. Commercial and industrial controls: Use in offices, warehouses, or retail spaces to automate lighting, signal occupancy, or drive building management actions. Integration notes Module form factor intended for electronic integration; requires a DC power source within 4.0–28.0 V and standard wiring to downstream lighting or alarm circuits. suited for projects and systems that need reliable, radarbased motion detection where optical sensors are less effective. Model and compatibility Model: RCWL0516 Core technology: Radar microwave induction module for movingobject detection This description preserves the RCWL0516 specifications: radar/microwave induction detection, sensitivity, long induction distance, large detection angle, reliability, and a wide operating voltage range of 4.0 V to 28.0 V, with common uses in human body induction lighting and antitheft alarm applications.
