Abstract
A distance-detecting sensor may include a housing, a focusing lens, and a circuit board. Infrared light may be transmitted by a transmitter and received by a receiver. The housing may include a main body having two apertures. A transmitting lens and a receiving lens may each be positioned within one of the apertures. The circuit board may be positioned above the transmitter and the receiver and below the transmitting lens and the receiving lens. The transmitter may be an infrared light emitting diode and the receiver may be a distance-detecting sensing module. A shielding case may be provided around the transmitter and the receiver to prevent electromagnetic interference.
