We’ve been having trouble with rodents (I assume squirrels) in the crawl spaces on our second floor. I decided to stick a PIR sensor on the door to see if I could catch any movement, and sure enough, a bunch of movement around 1 AM this morning.

@early_riser At some point I’m going to put a sensor in our crawl space. Mainly to track humidity but I’ve been debating including a motion sensor. Honestly I’m not sure I want to know how often things are lurking under the house!
As long as the sensor only picks up stuff that’s rat-size or larger then it’s fine. If there are something “large” down there, it can be a hazard to the house foundation. I’d say it’s better to know. 😉
Which motion sensor device do you prefer?
This is a Sonoff PIR sensor.
