Perfect for Arduino projects
This module works flawlessly with my Arduino Uno. The sensitivity adjustment via the potentiometer is very responsive, allowing me to fine-tune the vibration detection threshold easily. Great value for the price.

Excellent for learning sensors
Bought this for a university prototype. It responded instantly to taps and shakes. The dual LEDs make debugging very simple since you can visually see when the trigger activates. Highly recommended for beginners.

Reliable and compact
We use these in multiple student kits. They are robust enough to handle repeated plugging and unplugging on breadboards. The form factor is small enough to fit into tight enclosures without issues.

Works as advertised
Simple digital output makes coding a breeze. Just connect VCC, GND, and DO to an interrupt pin. The only minor downside is that the mounting holes are a bit close to the edge, but standard screws still fit.

Great sensitivity range
I was able to detect everything from a gentle tap to a strong shake by turning the blue potentiometer. No false positives in my final setup. Fast shipping and well-packaged too.

Good sensor, clear instructions needed
The hardware quality is solid and the soldering points are clean. It detected vibrations accurately in my security box project. I wish it came with a printed pinout diagram, but finding info online was easy enough.
Q: Can I power this directly from a 5V Arduino pin?
A: Yes, the module operates within a 3.3V to 5V range, so connecting it directly to the 5V pin on standard Arduino boards like the Uno or Mega is safe and recommended.
Q: Is this compatible with 3.3V logic systems like ESP32?
A: Absolutely. Since the operating voltage starts at 3.3V, it is fully compatible with ESP32, ESP8266, and other 3.3V logic microcontrollers without needing level shifters.
Q: How do I adjust the sensitivity of the vibration detection?
A: There is a blue potentiometer on the PCB. Use a small screwdriver to rotate it clockwise to increase sensitivity or counter-clockwise to decrease it until the signal LED behaves as desired.
Q: What is the maximum current consumption of this module?
A: The module typically consumes less than 20mA during operation, making it suitable for battery-powered projects where power efficiency is important.
Q: Does this module output analog or digital signals?
A: This module provides a digital output (DO). It switches between HIGH and LOW states when the vibration threshold set by the potentiometer is exceeded.
