10pcs RCWL-0516 Microwave Doppler Radar Motion Detector Module – Superior Motion Sensing for Diverse Applications

Product DescriptionThe RCWL-0516 is a compact motion detector module leveraging RCWL-9196 chip and Doppler microwave technology, designed to replace traditional PIR sensors with enhanced performance. It detects moving objects through glass and obstructions, making it ideal for scenarios where infrared sensors fall short.Key FeaturesMicrowave Sensing Advantage:Uses Doppler radar to detect motion, outperforming PIR sensors (e.g., HC-SR501/HY-SRF05) with better penetration through barriers like glass, ensuring reliable detection in varied environments.Adjustable Performance:Detection Range: Up to 7m (21ft) default; reduce to ~5m by adding a 1M resistor on R-GN pad.Delay Time: Default 2s; extend by mounting an SMD capacitor on C-TM pad (calculated as (1/f)×32678, where f is IC pin 3 frequency).Electrical Specifications:Voltage: 4V-28V input (5V-12V recommended); 3.3V output (≤100mA) on 3V3 pin for low-current devices.Current: 2.8mA typical, 3mA max for energy efficiency.Output: Switches from 0V (LOW) to 3.3V (HIGH) for 2-3 seconds when motion is detected.Practical Design:Compact size (35mm×17mm×3mm) with easy mounting; component side faces detection area for maximum sensitivity (back-side detection at lower sensitivity).Avoid metal objects within 1cm of the antenna to prevent interference.Versatile Applications:Ideal for DIY motion-sensor light switches, home/industrial security systems, human-sensor toys, and automated devices requiring reliable motion triggers.Technical DetailsOperating Temperature: -20°C to 80°C; Storage Temperature: -40°C to 100°C.Transmitting Power: 20mW (30mW max).Pins: 3V3 (3.3V output), GND (ground), OUT (control output), VIN (input voltage), CDS (CDS photodetector output).Pads: C-TM (delay adjustment), R-GN (range adjustment), R-CDS (CDS resistor connection).Package Includes10 × RCWL-0516 Modules
