The invention relates to a non-contact elevator sensing control device based on a photoelectron chip. The non-contact elevator sensing control device based on the photoelectron chip comprises the photoelectron chip which is used for emitting an optical signal to the outside, receiving the optical signal reflected by an external object and converting the received optical signal reflected by the external object into a photocurrent signal; the single chip microcomputer is connected with the photoelectron chip and used for sending a first control signal to an elevator connected with the single chip microcomputer after confirming that the size of the photocurrent signal is within a first threshold range and the duration time of the photocurrent signal is within a second threshold range. Non-contact sensing control of the elevator is achieved by detecting the optical signal, a two-stage mistaken-touch-preventing mechanism is adopted, the situation of mistaken triggering is reduced, and the accuracy and reliability of non-contact sensing are improved.
