Description

This module functions as a basic vibration-activated switch. An internal spring-mass system makes contact upon a physical shock or knock, causing the digital output pin to change state. The output is a clean digital signal, eliminating the need for analog-to-digital conversion and simplifying code logic for platforms like Arduino, ESP32, or Raspberry Pi.

The module’s design prioritizes straightforward integration, featuring a standard 3-pin interface (VCC, GND, Signal) and pre-drilled mounting holes for stable physical mounting, which is critical for consistent sensitivity. Its low power consumption and simple digital interface make it suitable for battery-powered or always-on monitoring applications.

Key Features

  • Digital TTL-compatible output for direct connection to microcontrollers.
  • Broad 3.3V to 5V DC operating range supports most development boards.
  • Compact form factor (19.5mm x 19mm) with integrated bolt holes for secure mounting.
  • Mechanical spring-based sensing element for impact and vibration detection.
  • High-value build optimized for prototyping and educational applications.
  • Simple 3-pin interface (Signal, VCC, GND) for quick wiring.

Applications

  • Intrusion detection and tamper alarms in security systems.
  • Impact monitoring for equipment health and predictive maintenance.
  • Interactive triggers for exhibits, art installations, or simple games.
  • Vibration detection in DIY robotics for collision sensing.
  • Basic activity monitoring in prototyping and educational electronics.

Frequently Asked Questions

What is the output signal type of this vibration sensor module?

The module provides a digital output signal. It outputs a logic HIGH or LOW voltage level based on the detection of a shock or vibration, making it directly readable by digital input pins on microcontrollers like Arduino or Raspberry Pi without requiring an ADC.

What is the operating voltage range, and can I use it with 3.3V systems?

Yes, the module operates from 3.3V to 5V DC. This wide range ensures compatibility with both 5V systems like standard Arduino Uno and 3.3V logic systems like ESP32, Raspberry Pi GPIO, and many modern microcontrollers.

How do I mount and calibrate this sensor for reliable detection?

Secure the module using the integrated mounting holes to the surface you wish to monitor. Calibration is not required for digital output. Sensitivity is fixed by the internal mechanical spring; ensure the module is firmly attached to effectively transfer vibrations.
