The invention discloses a transparent bottle liquid level sensor which comprises an upper frame, a lower frame and a hardware circuit system, the upper frame and the lower frame are connected through a fastening screw, and the mounting position of the fastening screw is filled with a gasket; a lens is mounted on the inner side of the lower frame and faces the inner side of the lower frame; the interior of the lower frame is provided with two groups of LED/PD assemblies corresponding to the lens, and the LED/PD assemblies are symmetrically arranged about the middle surface of the sensor. A PCBA is installed in the lower frame, and a connector is arranged on the back of the lower frame. The method has the advantages that a dual-wavelength detection scheme is applied for the first time, so that the liquid level of the transparent bottle body can be stably detected, and the interference of bubbles and water drops is avoided. An accurate teaching algorithm is adopted, and accurate setting can be carried out; by ad
