Perfect for my security project
This vibration sensor works flawlessly with my Arduino Uno. The sensitivity adjustment is very responsive, allowing me to fine-tune it so it doesn't trigger from minor background noise but catches any significant bumps. Great value for the price.

Great little module
Compact size fits perfectly in my small enclosure. The eco-friendly packaging was a nice touch. It detects even subtle vibrations when tuned correctly. Definitely buying more for future projects.

Solid performance
Used this in a prototype robot arm to detect collisions. The response time is quick enough for our needs. The potentiometer allows for precise calibration. Would have given 5 stars if it came with mounting screws included.

Good for learning electronics
Bought this for a school project using the micro:bit. It was easy to wire up and the example code found online worked immediately. The only reason for 4 stars is that the connector cable was a bit short for my specific setup, but otherwise excellent.

Easy to integrate
As someone new to sensors, I appreciated how straightforward this module was. The pinout is clearly labeled, and it responded instantly when I tapped the table. Highly recommend for beginners starting with Arduino.

Reliable and sensitive
I am using this to monitor vibrations on a washing machine to detect when a cycle ends. It has been running for two weeks without any false positives. The build quality feels solid and the LEDs make debugging very easy.
Q: What is the current consumption of this sensor?
A: The module consumes approximately 5mA when active. The power LED draws a small portion of this, but it is generally low-power enough for battery-operated projects.
Q: Is the output analog or digital?
A: This specific module provides a digital switching output (HIGH/LOW). When vibration exceeds the threshold set by the potentiometer, the DO pin goes LOW. It does not provide an analog voltage proportional to vibration strength.
Q: Can this detect sound vibrations or only physical shocks?
A: This sensor is designed primarily for physical shocks and mechanical vibrations. While loud sounds can cause physical vibration in objects, it is not a microphone and will not detect sound waves directly in the air.
Q: How do I adjust the sensitivity?
A: There is a blue potentiometer on the board. Turn it clockwise to increase sensitivity (detect smaller vibrations) and counter-clockwise to decrease it. Use a small screwdriver for adjustment.
Q: Does this module work with 3.3V logic levels like the ESP32?
A: Yes, the KEYES Vibration Sensor operates within a 3.3V to 5V range, making it fully compatible with 3.3V boards like the ESP32 and micro:bit.
