Very sensitive so it would come on if you walked past in another room behind a thick brick wall. Also never turned off and came on randomly. Not sure what the point of microwave instead of PIR is. Build quality isn't great and it is difficult to wire up as surface mounted. Returned as it doesn't work as described.
Great sensor, works as expected and decent quality
Nice little unit.
Easy to fit with built in screw terminal's block
Surface or recess mount
Simply twist on cover plate
No detection sensitivity adjustment, only for light level and time-on but works fine for my use detecting 4 meters either side in a hallway.
Detects past wooden doors by about half a meter so the lights are on just before entering.
Needs a sensitivity setting, but in all a great unit
