I like this better than any other vibration sensor I have tried. But I do not read Chinese. The adjustments on the board are written in Chinese, so I had to experiment a bit to figure out which one controls what.The adjustments are shown in the pic, and the one on the left is the time adjustment. The timer is a Delay-Off timer. When vibration is sensed, the output turns on the relay. Then, the timer holds the relay on until timing is elapsed and the relay turns off. Full CCW is the shortest time, probably 1 second. I do not know the max time, I did not time that.The adjustment on the right is the "sensitivity". However, if you were to rename that as "False Trigger Rejection", it would seem more accurate to adjust. Because it is more sensitive to vibration in the full CCW position. Turing the adjustment up (CW) turns the sensitivity down requiring more vibration to actuate the sensor. So that is why I say that if you think of it as rejection, with less being CCW and more rejection being CW...it makes more sense.I do not know if the sensor itself is a ball or spring type. But I think it just about has to be spring by the way it works. It requires a jarring motion, not movement, to actuate the sensor.While I have not gotten these in service yet, I have had them on my workbench to test. And as I say, they work better for my needs than the others I have tried. Those have used a ball type sensor, and do not have the option to time the output nor do they have NO or NC contacts. So these are much more versatile and better suited for my needs.You do need to test these before mounting them. The reason is because, in my testing, the spring sensor works better if the vibration comes from the side of it. So if you know where you expect vibrations to come from, you can mount it accordingly.Nothing not to like about them so far. And I do intend to mount this in a box and probably use hot glue to anchor the sensor module so it does not break the leads.

Mine didn't work right out of the box. It never senses the vibration and never trips the relay.

Red lights when powered, green when relay is active. Seems decently sensitive. I hooked it to a light /siren combo-Security Siren, Light and Sound Alarm, BRJ-102 / 12V Siren /Wired Strobe Siren/Red Light Flashing - to alert for a theft deterrent in a trailer.
