Abstract
A soap dispenser utilizes an infrared sensor for detecting the presence of an object upon which soap will be dispensed. There is a source of soap and a pump connected thereto. A voltage regulator having an adjustable output voltage to control the force at which soap is dispensed, and which may be considered a method of accommodating viscosity of soap, is connected to the pump. The sensor controls operation of the pump and there is an adjustable timing circuit to control the amount of time the pump operates and hence the volume of soap dispensed. A prime circuit is included to prime the pump as conditions require.
