Abstract
The present application provides a floor board unit, a floor board and an IoT home system. The floor board unit includes a floor board body which can switch between a light-transmissive state and a light-tight state, a floor board controller, a light emitting layer and at least one first sensor. The light emitting layer is below the floor board body. An output terminal of the first sensor is electrically coupled to an input terminal of the floor board controller. The light emitting layer is configured to emit incident light towards the floor board body. The floor board controller is configured to control the floor board body to be in the light-transmissive state when the light emitting layer emits the incident light. The first sensor receives reflected light obtained after the incident light is reflected and transmit a signal indicating an intensity of the reflected light to the floor board controller.
