Photoelectric mouse liquid-level sensor

The utility model discloses a photoelectric mouse liquid-level sensor, which is characterized in that the photoelectric mouse liquid-level sensor is provided with a float barrel, a height sensing part and a photoelectric mouse, wherein the float barrel floats on a liquid surface of a water level well and ascends and descends along with height of the liquid surface, the position of the photoelectric mouse is fixed, the photoelectric mouse detects relative position information of the height sensing part, and the relative position data signal which is utilized as a liquid-level detecting signal is recorded into a computer through the photoelectric mouse. The photoelectric mouse liquid-level sensor utilizes the computer technology, leads a float type liquid-level sensor to be combined with the computer directly, increases property stability when utilized as the liquid-level sensor, and realizes network transmission and remote monitoring.
