SW-420 Normally Closed Type Vibration Sensor Module

Digit switch output: 0, 1
Uses LM393 comparator.
Green light on when vibration switch is under closed conduction state and the output terminal is low
Green light off when vibration switch is disconnected and the output terminal is high
Great for microcontroller experiment
Output terminal can be connected to microcontroller to test electric level and if the environment is in vibration, alarm function
Suitable for a variety of vibration triggering functions, theft alarm, smart car, earthquake alarm, motorcycle alarm, etc.
