Description
The Mini Vibration Sensor Module is a compact and sensitive solution for detecting vibration, shock, and sudden movement in electronic projects. It is commonly based on a spring-type or SW-18020P vibration sensor with onboard signal conditioning, making it easy to interface with microcontrollers.
This module outputs a digital signal when vibration exceeds a certain threshold, enabling quick detection of knocks, impacts, or motion events. Due to its small size and low power consumption, it is widely used in anti-theft systems, equipment monitoring, alarms, and IoT-based security applications.
The module is fully compatible with Arduino, ESP32, ESP8266, STM32, and other microcontroller platforms.
