Frequently Asked Questions

What is the output signal type of this vibration sensor?

This module provides a digital TTL output signal. When vibration is detected, the output pin switches state (typically from HIGH to LOW), providing a simple on/off signal that can be read directly by a microcontroller's digital input pin without requiring an analog-to-digital converter.

What is the operating voltage range, and is it 5V tolerant?

The sensor operates from 3.3V to 5V DC. It is fully compatible with both 3.3V and 5V logic systems, making it safe to use with Arduino Uno (5V), Raspberry Pi (3.3V), ESP32 (3.3V), and similar development boards without risk of damage.

How do I connect this sensor to an Arduino board?

Connect the module using its 3-pin Gravity connector. The VCC pin goes to your board's 3.3V or 5V pin, GND to ground, and the digital output (D) pin to any digital input pin on the Arduino. You can then read the pin state using `digitalRead()` in your sketch to detect vibration events.

Can this sensor measure vibration intensity or amplitude?

No, this is a digital switch-type sensor. It detects the presence of vibration or shock above a fixed threshold but does not provide analog data on the intensity or amplitude. For quantitative vibration analysis, an analog accelerometer or a sensor with serial output (I2C/SPI) would be required.
