I ordered for my kid for experimenting with Arduino, he says they work great

Function: My order included 3 units. Each of these worked. The device has controls for adjusting duration triggered and sensitivity (detection distance). Once triggered the duration ranged 1sec to 6min. These values are consistent w/ the datasheet. I did not test sensitivity. Electrical Characteristics: Sensor pin output (Vout) range 3.19-3.33v across the input range tested (4-7v, datasheet recommended VCC range: 5-20v). PCB is approx. 24mm by 32mm (15/16inch x 1 1/4inch). Solder joints are clean. Would buy again.

Nifty little motion sensor. Easy to code and use with Arduino or Pico 2W. Nice feature is the ability to adjust time delay and sensitivity.
A**.
No repeated trigger connection and no LDR SLOT.
