    • Good sensor at fair price
Try starting with the sensitivity adjustment dial turned completely counter-clockwise and the delay dial completely clockwise. I found it a lot easier to tweak and troubleshoot at these settings and fine tune at the end. Also change the jumper on the underside unless you want repeat trigger mode. The component itself is durable enough and effective at the right settings. ... show more

    • Ay! took me two weeks to flip the sensor
So i didnt know there was an ultra sensor range and close proximit on the corner make sire yours is swiched the right way when you plug it in youre arduino.. And it should work.

    • Worked for my project
Bought these to use with a DIY ESPHome sensor to integrate with Home Assistant. They do exactly what I needed them to do...detect motion. I've read where they are 'more accurate" when using higher voltage (~12vdc), but they seem to work perfectly fine on 5vdc.

    • Seem to work just fine, good price
I attached this to a Raspberry Pi 2B w/o any issues and it seems to be working fine for the 2 or 3 days I have been using it. Got it set up to generate both e-mail and SMS when motion is detected using Python.

    • Works great as long as they're powered properly.
Review Image by Aaron Aaron
I had some trouble with these initially but it turned out to be due to a sufficient lack of power. I had loaded too many sensors onto my board and was getting a steady stream of false positives until I removed some sensors or added a capacitor. With Esphome these are very easy to integrate into my home automation. I've been slowly replacing my commercial Z-Wave and Zigbee motion sensors with these for the added flexibility and sensitivity. ... show more

    • Response time is sometimes low but overall a pretty decent sensor for home projects.
Been using it to turn my kitchen lights on and off automatically for a few months now. Works mostly fine. Sometimes there is a lag right after it turns off. But overall pretty decent.

    • takes some fine tuning but they work
I got these because I had some from ali that started having issues. These worked fine and it was nice to be able to control the time out and sensitivity.
