Beschreibung
Zusammenfassung:	The invention discloses a rainfall and sunshine sensor, which comprises an optical shielding cover and a PCB (Printed Circuit Board) arranged in the optical shielding cover, wherein there is an innerprojection layer between the PCB and the inner fixed wall of the optical shielding cover, and the outer surface of the optical shielding cover is provided with an outer projection layer; the optical shielding cover is provided with a light outlet and a light inlet in a penetrating manner, the surface of the PCB is provided with conical holes and through holes in a penetrating manner, the lower surface of the PCB is provided with an infrared receiver and an infrared transmitter, the light emitted by the infrared transmitter passes through the conical hole, the inner projection layer and the light outlet and is projected to the outer projection layer, the infrared receiver receives the light projected from the through hole. The rainfall and sunshine sensor has the advantages that the opticalpropagation path is chang
