Capacitive fluid detection system for a pump

Abstract

Disclosed herein are a pump and a method for controlling the pump for detecting a fluid around the pump based on a value detected by a capacitive sensor. The pump may include a motor housing accommodating a motor configured to drive an impeller to discharge fluid. The pump may include a pump cap, located above the motor housing, accommodating a controller configured to drive the motor. The pump may include a sensor box, provided on a side of the pump, accommodating a capacitive sensor. The controller may be configured to drive the motor after determining that a value detected by the capacitive sensor indicates that the fluid is present around the pump.
