Vibration Sensor Module SW1801P

The Vibration Sensor Module SW1801P is based on the SW1801P spring-type vibration switch, which reacts to slight shocks or movement. Inside the sensor is a conductive spring element that momentarily connects when vibration occurs, generating a pulse signal.
The module includes a signal processing circuit with a comparator, sensitivity resistor, and indicator LED to provide reliable digital switching output. It can be easily interfaced with development platforms such as Arduino, ESP, STM, and Raspberry Pi for motion or tap-based event sensing.
Due to its fast response, low power consumption, and high sensitivity, it is ideal for anti-theft systems, smart appliances, electronic toys, step counters, and vibration-triggered monitoring systems.
