The invention discloses an optical cone measuring sensor. Two light paths forming a fixed incident angle with a plane lens (2) are arranged in a light path adjusting module (3); the visible light wave band light penetrates into the light path adjusting module through the plane lens (2), is received by the photosensitive device (7) and is converted into a current signal; the photoelectric conversion module (4) converts the current into a voltage signal; the signal conditioning module (6) converts the voltage signal into a photoelectric pulse signal after amplifying, shaping and modulating; the digital processing module (5) triggers the timer by collecting edge signals of the photoelectric pulse signals, and the waving height and the swinging angle of the paddle are calculated. The final calculation of the cone data is realized in the optical cone measurement sensor, the signal loss and interference in the external transmission process are reduced, and the precision of the calculated cone data is higher.
