VIBRATION SENSOR SW420 MODULE

The SW-420 Vibration Sensor Module is a vibration detection module designed to sense shocks, vibrations, and sudden movements in electronic systems. It is based on the SW-420 vibration sensor and an LM393 comparator, providing both digital (DO) and analog (AO, on some versions) outputs for easy interfacing with Arduino, ESP32, STM32, Raspberry Pi, and PIC microcontrollers. The module features an adjustable sensitivity using an onboard potentiometer, low power consumption, fast response, and stable performance for reliable vibration detection. Due to its compact design and high sensitivity, the SW-420 Vibration Sensor Module is widely used in security alarm systems, industrial equipment monitoring, earthquake detection, machine vibration monitoring, robotics, IoT devices, and embedded system applications.
