Microwave Radar Sensor Module (RCWL-0516)

Microwave Radar Sensor: Precision Motion Detection

Our microwave radar sensor uses 3.2 GHz radar pulses to “see” movement through walls and glass. Feel the silent scan as it detects even the smallest gestures in total darkness.

RCWL-0516 Module: Compact & Powerful

This RCWL-0516 module packs microwave radar sensing into a 15×30 mm PCB. Slip it into tight spots—its low-profile design hugs corners and blends inside devices.

Motion Detection Sensor: Always On Guard

As a motion detection sensor, it triggers in under 50 ms. Imagine lights snapping on the moment you step into a hallway—no delay, no fumbling in the dark.

Radar Sensor Module: Weatherproof & Durable

Housed in a sealed shell, the radar sensor module resists dust and light rain. Run it outside or inside—its stable performance never falters, come wind or shine.

PIR Sensor Alternative: Smarter Sensing

Unlike PIR sensors, the microwave radar sensor penetrates obstacles and tracks speed and direction. It hears your approach before you even see the light change.

Microwave Sensor Module: Easy Integration

Wire it in seconds with three pins—VCC, GND, OUT. Use our Arduino library for instant setup. The microwave sensor module fits any microcontroller with a 3.3–5 V input.

Story Behind the Sensor

Frustrated by false PIR triggers in windy conditions, our engineers turned to radar. Late nights in the lab yielded the RCWL-0516 design, merging reliability with micron-level motion detection.
