    I found these to be really useful and a lot of fun to play with. Ordered another 2 to use on projects because they are so handy. I used 2 on little, mobile, burglar alarms with strobe lights and a high-pitched buzzer. Like a smoke detector only with a continuous sound. They can be placed quickly anywhere you want to protect. Robust, reliable and very reasonably priced. Great buy!

    I've tried a number of different PIR sensors and this is by far the best so far. It puts out a really usable voltage, which I've found enough for all my applications so far. Build quality is very good and sensitivity adjustment is excellent and repeatable. I'm using one of these teamed up with a digital counter to count the number of rats using a track in an old barn.

    very sensitive. work every time. Be aware that it does not recognize day or night. I attached it to the exhausting fan in the restroom. It turns on very time people walk near by.

    It works well. i have it connected to my car cam so when i enter the car the cam turns on. i have lights overhead and they are on all the time. this turns them on and off.

    The sensor is very small, but is sensitive from far and near too. I use it to switch on four 3W 12V LED lamps, so around 1A is switched. It was installed a week ago, and no problem since then.
