One (of 5) needed soldering
One sensor was not working, but I tracked it down to a bad solder joint on the sensor module. ( I have a different issue now, but I believe it to be my wiring, so I will not report it here.)

Compact size PIR motion sensor
This is compact size PIR motion sensor. The price seems to be good for a batch of 5.

Turs on at least once a minute
These turn on when in a room with nobody in it. I bought them for an alert system, so they are useless to me.

Do NOT purchase these sensors
Do NOT purchase these sensors. They do not work due to very poor manufacturing quality. The first one I opened from packaging had wires not soldered to the board correctly. Thus it failed to work. And so it continued. Since I have no way to contact the seller, I can't request any replacement for faulting components. In the photo above, one sensor has wires NOT soldered at all. And another sensor, the wire is soldered but it is in the incorrect position such that it fails to work. Did anyone do any quality control? Apparently NOT.
