Too Sensitive
The sensor is very sensitive, maybe too much for my specific application. It took a lot of tweaking to get it right. Works fine if you need high sensitivity.

Perfect for Arduino Projects
This sensor module works exactly as described. I used it for a security box alarm and the sensitivity is easy to adjust with the potentiometer. Highly recommended for beginners.

Good Sensitivity
Works well overall. Had to spend some time calibrating the sensitivity to avoid false positives, but once set up it is very reliable. Good value for the price.

Great for Alarms
Using this for a DIY home security system. It detects vibrations from windows and doors effectively. The LED indicator is helpful for debugging during setup.
Q: Can I adjust the sensitivity level?
A: Yes, there is a blue potentiometer on the board that allows you to adjust the sensitivity threshold for detection.
Q: Does this output analog or digital signals?
A: This module outputs a digital signal. It switches between High and Low states when vibration or free-fall is detected.
Q: How should I mount this module for best results?
A: For optimal performance, secure the module firmly using the mounting holes to ensure vibrations are transferred effectively to the sensor.
Q: Is there a specific library required for this sensor?
A: No specific library is needed. You can read the output pin using standard digital read functions in your preferred coding environment.
Q: Is this module compatible with 5V logic systems?
A: Yes, this module operates comfortably between 3.3V and 5V DC, making it compatible with most standard microcontrollers like Arduino and Raspberry Pi.
