Good value for money
Solid build quality for the price. It penetrates non-metallic materials well, which is great for mounting inside boxes. Just be aware it can detect movement outside a room if the walls are thin.

Great sensitivity, needs calibration
Works exactly as described. The detection range is impressive, perhaps too sensitive for small rooms unless you add a resistor to the C-TM pin. Very easy to integrate with ESP32.

Easy for beginners
I was worried about wiring this up, but it's just three pins. Connected it to my Arduino Uno and had the LED blinking within minutes. The documentation online is very helpful too.

Superior to PIR for my project
This microwave sensor is fantastic. Unlike standard PIR sensors, it detects motion through thin plastic enclosures and doesn't require a direct line of sight. Perfect for my hidden security setup.

Exactly what I needed
Replaced my old infrared sensors with these. The difference in detection reliability is night and day. No more false negatives when walking slowly. Highly recommended for automation projects.

Reliable and compact
Bought five of these for a hallway lighting project. They trigger instantly when someone walks by and reset quickly. The form factor is tiny, making them easy to hide behind fixtures.
Q: Does this work with 3.3V logic microcontrollers like ESP8266?
A: Absolutely. Since the output high level is approximately 3.3V when powered at 3.3V or 5V, it is fully compatible with ESP8266, ESP32, and other 3.3V logic boards.
Q: What is the maximum voltage this module can handle without damage?
A: The module operates safely between 3.3V and 5V DC. We recommend staying within this range to ensure longevity and stable performance.
Q: Will rain or wind trigger false alarms if used outdoors?
A: While the sensor is robust, heavy rain or strong wind moving objects within the detection zone may trigger it. We recommend using it in a sheltered location or adjusting sensitivity for outdoor use.
Q: Can this sensor detect motion through a wooden door?
A: Yes, the RCWL-0516 uses microwave radar technology which can penetrate non-metallic materials like wood, plastic, and thin drywall effectively.
Q: Is it possible to adjust the detection distance?
A: Yes, you can adjust the sensitivity and detection range by soldering a resistor to the R-GN pads on the board. Refer to the datasheet for specific resistance values.
