Reliable and sturdy
Been using this in a prototype for two weeks now. It hasn't given any false positives once I dialed in the threshold. The build quality feels solid, and the LEDs provide good visual feedback during debugging.

Exceeded expectations
Very impressed with the precision. I tried several cheaper modules before, but this Hancheng original sensor is much more consistent. It triggers exactly when I tap the surface, no lag.

Great value, clear documentation
Good quality module for the price. The pinout is clearly labeled, and it interfaced easily with my Arduino Uno. Only giving 4 stars because the included pins were slightly loose, but that's a minor issue.

Good for learning sensors
Bought this for a university project. It was easy to integrate into our circuit. The sensitivity range is wide enough to experiment with different thresholds. Would recommend for educational purposes.

Perfect for my security project
This vibration sensor is incredibly sensitive. I used it to detect knocks on a door for a smart home alarm system, and it worked flawlessly right out of the box. The adjustable potentiometer makes tuning the sensitivity very easy.

Highly responsive
I needed something to detect vibrations on a machine for predictive maintenance testing. This piezo element picks up even subtle changes. The dual output (analog and digital) is a great feature for different use cases.
Q: Can this sensor detect sound waves or only physical vibrations?
A: This is a piezoelectric vibration sensor designed to detect physical shocks, knocks, and vibrations transmitted through the surface it is mounted on. It is not optimized for detecting airborne sound waves like a microphone.
Q: Is there a library available for Python/Raspberry Pi?
A: Since this module outputs a standard digital or analog signal, you do not need a specific library. You can read the state using standard GPIO libraries like RPi.GPIO or gpiozero by reading the pin state.
Q: What is the maximum current consumption of this module?
A: The module consumes very little power, typically around 4-5mA when active. The standby current is significantly lower, making it suitable for battery-powered applications.
Q: Does this module come with header pins soldered?
A: No, the module typically comes with unsoldered header pins in a small bag so you can choose to solder them straight or at an angle depending on your project needs.
Q: How do I adjust the sensitivity?
A: There is a blue potentiometer on the board. Turn it clockwise to increase sensitivity (detect lighter taps) and counter-clockwise to decrease sensitivity (require harder knocks to trigger).
