PURPOSE: A water level sensor using a float level sensor is provided to increase the simplicity of installation thereof by supplying operation power using a solar cell. CONSTITUTION: A water level sensor using a float level sensor comprises a water level sensing pipe(100), a float level sensor(170), an upper body(130), and a controller. The water level sensing pipe is built in a location that senses the water level of a place such as a river and a reservoir The water inlet, in which water flows, is formed on the lower part of the water level sensing pipe. The water level sensor it is installed downward in the inner side of the water level sensing pipe. The upper body is installed on the upper end of the water level sensing pipe. An information display window for displaying various kinds of information, including the water level information of external diameter, is formed in the upper body. The controller is installed in the inner side of the upper body. The controller determines water level using the value detected by the float level sensor. The controller is displayed in the information display window and transmits the detected water level information to a remote site through a communications part.
