ABSTRACT:
A water level controller for a pool has a water level sensor immersed in the pool. A processor detects if the sensor senses low water. A transmitter sends a radio frequency signal to a receiver if the processor detects the low water. The receiver turns on a valve to add water to the pool. The transmitter and processor are contained in a waterproof housing. A main power switch is located internally in the housing, and moves between on and off positions by inverting the housing. A wave filter timer within the processor turns on for a selected interval when the processor detects low water. The receiver has an overfill counter that turns on for a selected interval when the receiver receives the low water signal. The receiver resets the overfill counter prior to reaching the selected count each time that the receiver receives a low water signal.
