DESIGN AND CONSTRUCTION OF TOUCH FREE WATER DISPENSER MACHINE
Abstract
ABSTRACT
A water dispenser is a system or a machine which is designed and capable of responding to an instruction or request made by the user in other to dispense a particular liquid . This paper developed a touch free water dispenser that eliminates manual operations of the dispenser’ pumps . This is achieved by the use of ultra sonic sensor in the control unit that automatically detects the presences of hand holding cups or other container. It also solves the issues of overflow of fluid due to loss of concentration by the tap operator. The system built with arduino microcontroller. The outcome at the end of the specified designed period was a working prototype below the sensor. The result shows that ultrasonic sensor carries out it sensing functionality satisfactorily
