The principle of the Light-controlled Fan Kit is as follows:
When the light is bright enough, the small fan can rotate.
If the indoor small fan does not rotate during the day, you can take out a flashlight or phone and directly illuminate the photosensitive resistor, and the small fan can tell to rotate.
Light control does not mean that it will rotate when there is light, but it means that the light intensity reaches a certain level.
