This is a 2 wire connection, not three as implied by the board picture/description.The board (+) is not connected.The board a 1M resistor between Signal and Gnd.The Zener has it's Cathode connected to Signal (S) and Anode connected to Gnd

I bought these for a drum light kit I'm building... and I read from the internet that piezos are capable of putting out a lot of voltage in spikes if hit hard enough, up to 90v! That's way more than the 5v that an arduino can handle.This is essentially a Zener diode with a 1Mohm resistor inline, so that if the voltage gets too much, the circuit will shut down instead of frying your stuff. So far they seem to be working well, even though my project has not yet come to fruition.

It’s pretty much impossible to attach the very small piezo wires to that large connector. I ruined one connector trying to tighten it. Cannot tell if the device works.

The media could not be loaded.

These worked exactly as I needed. With this and an ADC I was able to get these to detect impacts exactly as I needed, and also 5 of them for this price was reasonable.

Red hot garbage, the piezo sensor might be ok if taped to the side of a big bass drum but it could not be triggered by a vibrating phone. the tiny wires coming off the sensor are very difficult to connect to the terminal block as they are finer than frog hair. I was able to solder some thicker wires and that helped a bit.Overall this product is a fail from my experience.
