PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range, excited for long term use. So far it looks like its working as advertised. Satisifed
These are small, inexpensive, low-power, easy to use and don't wear out. Honestly this is exactly what my dad was looking for.
Didnt know what to expect with this but it surpassed my expectations.
Everything came quickly, well packed. Looks like a good thing, ill test for a few weeks then add a more comprehensive review
