The SW-420 Vibration Sensor is a small and inexpensive sensor that is designed to detect vibrations and movements. It is commonly used in electronic projects and applications that require motion sensing, such as alarm systems, anti-theft devices, and vibration-based controllers.
The sensor contains a metal spring that is surrounded by a coil. When the sensor experiences vibrations or movements, the spring will compress or expand, causing changes in the coil’s electrical properties. These changes can then be detected and measured by a microcontroller or other electronic devices.
The SW-420 Vibration Sensor is easy to use and requires only a few external components to operate. It has a digital output that can be connected to a microcontroller’s input pins or other digital input devices. The output signal is high when the sensor detects vibrations or movements, and it becomes low when there are no vibrations or movements.
