Smart urinal with multi sensing electric fields

Abstract

A smart urinal with multi sensing fields comprises a urinal body, two or more proximity capacitive sensing electric field means and a flushing control unit. A urinal body, a urinal facade which forms a basin, and a cavity arranged inside the urinal body. The two or more proximity capacitive sensing electric field means, which are arranged in the cavity; an proximity capacitive sensing electric field is formed around the proximity capacitive sensing electric field means; said proximity capacitive sensing electric field means individually generate proximity capacitive Sensing information according to a change of the electric field energy caused by the proximity capacitive sensing electric field corresponding to a sensed object. The flushing control unit, which receives the proximity capacitive sensing information, and controls the bowl area flushing according to one or more logic operation results in the received proximity capacitive sensing information,
