Review on ⚡️ DIYmall RCWL-0516 Motion Detection Sensor: Microwave Radar Switch Module for Arduino ESP8266, Raspberry PI - Human Rat Cat Detector - Detection Distance 5-7m by Charles Collier
Sensitive, sees 7 meters as advertised, works in Raspberry PI
I put together a little media jukebox for goodies (like we'll have some of that this year, but who knows) and I'm using this instead PIR. It has a good range (around 21 feet as advertised) and is sensitive and fast. A bit difficult to test in development as it perceives all vibrations as movement at close range. The circuit itself is very clever, the radar on the trace! It accepts 5V and outputs a 3 by 3 signal as well as a 3 by 3 reference voltage (although I don't know how much current it can output). Extremely simple and easy to use.
- Sturdy build
- Was damaged
