RCWL-0516 Microwave Radar Doppler Motion Detector Sensor Module
Mini Doppler radar motion sensor module alternative to traditional PIR motion sensors, capable of detecting movement through wood, glass, and plastic enclosures.
RCWL-0516 Microwave Radar Doppler Motion Detector Sensor Module is an original, pre-tested electronic module designed for Arduino, ESP32, Raspberry Pi, robotics, and embedded engineering projects. Includes verified pinout compatibility and nationwide express shipping across Pakistan.
The RCWL-0516 Microwave Radar Sensor uses Doppler radar technology to detect moving humans and objects. Unlike standard PIR motion sensors, it can see through non-metallic enclosures.
Key Engineering Features:
- Penetrating Radar Waveform: Transmits 3.18 GHz microwave pulses that pass through glass, wood, acrylic, and 3D printed plastic enclosures.
- 360-Degree Sensing Sphere: No blind angle detection pattern with up to 7 meters range.
- High Immunity to Temperature Fluctuations: Reliable operation in hot Pakistani summers where PIR thermal sensors fail.
- Clean Digital Output: Outputs a clean 3.3V high logic pulse when motion is detected.
Common Engineering Applications:
- Concealed smart home motion sensors hidden behind walls or inside 3D casings
- Automatic corridor and staircase lighting switches
- Anti-theft vehicle and room intrusion alarms
- Automated contactless sanitizer dispensers and door triggers
What's Included in the Package:
- 1x RCWL-0516 Microwave Doppler Radar Motion Sensor Module
- 1x 5-Pin Male Header Strip
Pinout Interfacing & Testing Guide:
Check the silkscreen pin labels (VCC, GND, SDA/SCL or I/O) and confirm whether your microcontroller uses 3.3V or 5V logic.
Wire the power, ground, and signal pins to your Arduino, ESP32, or Raspberry Pi using breadboard jumper wires.
Upload a standard test sketch via Arduino IDE or MicroPython and verify live readings on the Serial Monitor.
