Device does what it should, the adjustment is VERY sensitive. Signal is very brief, but if you’re looking for a quick trigger DO, this does the job

Very good. Very sensitive but not too much false alarm. Sensitivity seems responsive to adjustment. Overall very good device and value.

Worked but not as expected. I can only measure tilt one direction. It would be better if the out put was not analog but digital using a comparator chip.

It is a mechanical sensor, not piezo. It only works erratically. I think it is at rest on a closed circuit and trips when circuit is open, which would explain why some one else has battery life issues and why it sometimes stays on until tapped. I figured id pull it apart out of curiosity since it wont work for my purposes as a knock knock light.

This works great with arduino and esp products.

It probably comes as no surprise the sensor is quite directional. This is due to the way it's mounted on the PCB, and the "sensor" itself. I was expecting it to be spring-based like the common SW-18010P/SW-18020P/SW-18030P vibration sensors available from Adafruit. But it's just a "dog-bone" in a tube. You can even see another set of through-holes, presumably for an upright sensor.It's basically impossible to adjust the sensitivity to what you want. The potentiometer does something, but it can't magically fix the useless sensor output. Additionally, as another reviewer mentioned, the comparator occasionally latches high. The signal is always noisy and bouncy. It's a shame, the PCB is nice enough, but it just doesn't work reliably.I'd avoid this. Although it's harder to interface with, an accelerometer is better at detecting vibration/motion. Other vibration sensors containing springs may also be better.

Very good stuff.
