Reliable module
Used in multiple projects now. It handles 5V logic well and the output is clean for microcontroller input.

Great for learning
Works perfectly with my Uno kit. I used it to create a simple vibration alarm and the sensitivity adjustment is very handy.

Good sensitivity
Needed some tuning with the potentiometer to get it right for my project, but once set up it works consistently.

Okay for price
Works but very sensitive. It triggers easily even with minor movements nearby, so careful calibration is required.

Fast delivery
Arrived well packaged and quickly. The module looks sturdy and the soldering points are clear for beginners.
Q: Do I need an external resistor?
A: No, the module has built-in components including the comparator and pull-up resistors ready for use.
Q: What is the maximum vibration it can detect?
A: It detects physical shocks and vibrations on the module surface. It is designed for hobbyist sensitivity levels.
Q: Can I use it for sound detection?
A: It is designed for physical vibration contact, not for detecting air pressure sound waves like a microphone.
Q: Can it work with 3.3V logic?
A: Yes, it supports operating voltages from 3.3V to 5V, making it compatible with most modern microcontrollers.
Q: Is this analog or digital output?
A: This module provides a digital output signal (HIGH or LOW) based on the vibration threshold you set.
