Spec:
- Working voltage: 3.3V~5V
- Current: > 15mA
- Uses SW-420 normally closed 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.
