I've 20 years of programming experience but not hardware involved and planning to start with raspberry pi just for fun.
Willing to do some testings with motion sensors and stepper motors. I've checked this motion sensor (HC-SR501) but all the tutorials I've watched are done with human motion. My plan is to detect motion of non-living things, objects.
Does HC-SR501 detect objects or is there some other kind of sensor?
Edit (Link to the sensor)
This is the sensor I refer to
