Works fine but definitely not 360 degree detection
I am still experimenting, range at 5V is about 2-3m. and its pretty directional not the 360 claimed. I am using it with a WeMOS D1 Arduino also from MPJA and Home Assistant, lots of fun. See

New use
Just mounted one of these into A Mason Jar connected to a low power transmitter. Now have a driveway alarm for less than $5.00! Use my Ham rig as the receiver. Solar powered to boot.

Unbelievable price for a radar
Worked to about 18 feet. Draws about 2.8 mA in standby.

Very sensitive
This detects human motion even thru an interior wall! Range about 20 feet, bigger objects perhaps further. Easy to hook-up and very low power.
