Reliable vibration detection
I integrated this into a custom smart home alarm system. It reliably detects vibrations from glass breaking simulations without false alarms once calibrated correctly.

Solid component
The build quality is decent for the price. The piezo element is well-secured. Just make sure you read the pinout diagram carefully before connecting power.

Good value, easy to use
Works as described. The digital output makes it very easy to interface without needing an ADC. Only giving 4 stars because the soldering points are a bit small for beginners.

Great for student workshops
Bought a batch for our robotics club. Students loved building tap-switches for their robots. The documentation provided was clear and helped them understand the circuit quickly.

Exceeded expectations
Very responsive to touch and vibration. I used it to create a musical instrument prototype, and the latency is negligible. Highly recommended for creative projects.

Perfect for my security project
This piezo sensor is incredibly sensitive. I adjusted the potentiometer to detect even light taps on my window frame. The included code worked straight out of the box with my Arduino Uno.
Q: Can this detect continuous vibration or only taps?
A: While optimized for tap detection, it can detect continuous vibration if the amplitude exceeds the threshold set by the potentiometer. However, the output is digital, so it will remain HIGH as long as vibration is detected.
Q: Is the sample code compatible with the ESP8266?
A: Absolutely. The provided program data includes examples for standard Arduino IDE, which fully supports the ESP8266 and ESP32 platforms.
Q: How do I adjust the sensitivity of the sensor?
A: There is a blue potentiometer on the board. Turn it clockwise to increase sensitivity or counter-clockwise to decrease it until you achieve the desired detection threshold.
Q: What is the maximum current draw of this module?
A: The module consumes very little power, typically around 5mA when active. It is safe to power directly from the GPIO power pins of most development boards.
Q: Does this module work directly with 5V logic levels?
A: Yes, the module operates comfortably within the 3.3V to 5V range, making it compatible with both 3.3V and 5V microcontrollers like Arduino and ESP32.
