I didn’t bother to test out all of the sensors, but for the few I’ve used in my stm32 project it worked as expected.

Seems to be a good product for the price
I haven’t checked accuracy yet or motion detection in a larger room, but seems to work well so far.

I love shopping. Great stuff, great prices and I have never bought a dud from these people. These are popcorn PIR sensors with some output customization available on board. Nice and sensitive.
