KY-002 Vibration Sensor Module is a compact shock and vibration detection sensor designed for Arduino, Raspberry Pi, ESP32, and other microcontroller-based electronics projects. This module detects vibration, impact, knocking, and sudden movement using a vibration switch mechanism and provides a digital output signal that can be easily processed by a controller. ([iFuture Technology][1]) The KY-002 vibration sensor module is easy to use with a simple 3-pin interface, low power consumption, and small PCB design. It is suitable for security alarm systems, anti-theft devices, robotics projects, smart home applications, industrial vibration monitoring, and interactive electronics projects.

• Suitable for beginners, students, hobbyists, and professional electronics developers.
• Can detect vibration from different directions depending on installation position.
• Includes onboard resistor circuit for stable digital signal output.
• Designed for quick integration into automation and control systems.

How to Use:

• Connect the VCC pin of the module to a 3.3V or 5V power supply.
• Connect the GND pin to the ground connection of the controller.
• Connect the S (Signal) pin to a digital input pin of Arduino, Raspberry Pi, ESP32, or another microcontroller.
• Upload a suitable program to read the digital vibration signal.
• When vibration or shock is detected, the module sends a digital signal to the controller.
• Use the detected signal to trigger alarms, LEDs, motors, notifications, or other electronic actions.

Applications:

• Arduino vibration sensor projects.
• Shock detection and impact monitoring systems.
• Anti-theft alarm systems.
• Door and window vibration security sensors.
• Smart home automation projects.
• Robotics movement detection systems.
• Industrial machine vibration monitoring.
• Electronic toys and interactive devices.
• IoT vibration monitoring projects.
• Wearable electronics and activity detection systems.
• DIY alarm circuit development.
• Educational electronics experiments.

Working Principle:

• The KY-002 module uses a vibration switch mechanism that detects physical movement and vibration.
• When vibration or shock occurs, the internal switch changes state and generates a digital output signal.
• The connected microcontroller reads this signal and performs programmed actions.
• The module provides a simple solution for detecting mechanical movement without complex programming or calibration.

Technical Information:

• The sensor module works as a digital vibration switch rather than an analog vibration measurement sensor.
• It provides ON/OFF type detection output based on vibration or impact.
• The module is designed for simple interfacing with development boards.
• Suitable for projects requiring vibration event detection rather than precise vibration measurement.
