From the shop's description

Tilt Sensor Vibration Alarm Vibration Switch Module sw18010p 4 pin Vibration Sensor Module Normally Opened Type SW18010P Vibration switch alarm sensor module for Arduino Module use: For a variety of vibration triggering, reported theft alarm, intelligent car, electronic building blocks. Please note that this module triggers a very short time upon sensing a big shock, not enough to drive the relay, the data show that some people can be connected directly to the relay module, the practical application ineffective. Module Description: Use of the company’s high sensitivity vibration switch SW-18010P default with vibration sensors. The comparator output signals clean, good waveform, driving ability, than 15mA. Working voltage of 3.3V-5V. The output form: digital switching output (0 and 1). A fixed bolt hole for easy installation. Small PCB board size: 3.2cm x 1.4cm Using a wide voltage comparator LM393. Module Wiring Instructions: VCC: positive power supply GND: negative one DO: digital signal output AO: With this shock sensor this function is invalid
