Range is limited

Works as described but 5 meters is optimistic in cluttered rooms. Good for small spaces.

Better than PIR

Finally a sensor that detects presence without large movements. Very reliable.

Perfect for ESPHome

Integrated this into my smart lighting system. The micro-motion detection prevents lights from turning off while I'm reading.
