These motion sensors work great!
These motion sensors are great for home automation. I have several hooked to esp boards around my house and use home assistant to control lights when the PIR detects motion. Good quality and easy to hook up.

Fast service, good pricing and 100% functional
These sensors are a good value for the money, every order has arrived on time and I've never received a dud. That's 5 stars.

Works as expected and is a nice format for my project.

No need to adjust and works best on at least 5 volt power.
I have had good luck getting these PIR to work reliably. Some other PIR did not work as well.

Great product - Awesome range
I wasn't expecting the range of 15'+ indoors. All were functional.

Doesn't work
Installed, worked twice, and then didn't work again.

Work well, somewhat bent.
The sensors work well but are not even close to being straight on the PCB they're mounted to. Because of the way the sensor is soldered to the PCB, it will just tilt another direction if you try to correct the bend. All in all they are a good value for the price if tight tolerances aren't a concern.

Great value
I have been using SR501s for years. These are so much better. The are physically smaller, much easier to mount in a project box. Most importantly, they appear to have a slightly narrower field of detection, which I like and DON'T SEEM to have the false triggers.As long as you are using it with a micro controller, as I am, the ESP32, the fact that you can't change the trigger time is not an issue. I also like the fact that the sensitivity is fixed since it means I just install and go, no need to calibrate or set up.
