These sensors are really good, they detect motion from far away. If you test it and you only get 1 trigger you just need to set the potentiometers on the board, it will become a lot More sensitive then. If you're following the Micro Python book it suggests to leave as is but my two sensors both needed tweaking. Make sure you buy the female to male jumper wires.

The module is very easy to use and convenient for use with either a pi or pi pico. It requires 5v supply but the sensor output is 3.3v logic levels, so it can plug straight into a Pi GPIO pin with no extra components needed. On a Pi Pico you can get 5V off the "VBUS" pin assuming that the pico is powered by USB. The module generally works well and can detect a person indoors quite reliably several feet away. My application though was a bit different. I was trying to detect next door's cat outside. It can indeed detect the cat, but unfortunately when outdoors it false positives too often. I had it tuned down to minimum sensitivity pointing at a fence and it would false positive about every 20 minutes. The fence is stable and there's nothing obviously moving at all in the wind. I put a heavy rock on top of my project box to make sure the sensor wasn't moving. It might be temperature contrasts causing it to false positive maybe. So it's not useful for this application. It would be fine for something like taking a wildlife photo outdoors where you don't care if you get a lot of dud pictures.
