Aqara Vibration Sensor Amplifier

Making a vibration sensor work when slapped on a washing machine can be very tricky. Even with sensitivity set to high, the sensor may still not sense vibration if the device doesn't shake enough.

To solve the issue I looked online for a solution but couldn't find any. Then this idea came to my mind. Very simple, very basic, but it works! A very gentle knock on the washing machine shakes the sensor really well, while initially this would required a strong blow with my fist to register a vibration.

Your feedback is highly appreciated. I'll update the design based on your suggestions/testing.

Edit: Uploaded V2 model which is less sensitive to vibration compared to V1. Useful if you don't want the sensor to register super tiny vibrations.
