Descriptions: The VCC external 3.3-5V voltage, GND with an external GND, DO small board digital output interfaces (0 and 1), AO small board analog output interface. Comparator chip LM393 ,it is stable. This module usually used for detecting the vibration intensity. When vibration intensity can not the value,DO output is high level.When vibration intensity over than the value, the module DO output is low level.
