The product is driven by the fan to rotate the magnet, and as a result, the aluminum plate connected to the pointer will generate some eddy currents. At the same time, the magnetism of the field magnet and the magnetism of the eddy current on the aluminum plate will also attract and repel, along with the speed of the blade. The faster the pointer is, the higher the wind direction is. The thermometer measures temperature changes, and the cup measures rainfall.

 

Fundamental Principles:

- Wind direction

- Thermometer

- Wind speed

- Precipitation

- Rainfall
