  "textContent": "The present invention discloses a distance detecting sensor, comprising: a housing, a focusing lens, a circuit board provided with several electronic elements, as well as a transmitter device for transmitting infrared light rays and a receiver device for receiving and sensing the reflected infrared light rays, wherein the housing comprises a main body and two circular apertures located on a top surface of the main body; the lens comprises transmitting lens and receiving lens disposed at positions of the apertures of the housing; the circuit board is installed in the main body of the housing; the transmitter device is an infrared light emitting diode, for transmitting the infrared light rays to the transmitting lens; the receiver device is a distance detecting sensing module, for sensing the reflected light rays focused by the transmitter device. The distance detecting sensor further comprises a guiding device for transmitted light rays installed between the transmitting lens and the transmitter device, the guiding device comprising a small circular hole located in the position of a transmitting tube core of the transmitter device. The present invention enables a relatively high detection precision, improving the sensing performance as a whole.",
