Automatic Dispenser Prevents Covid Transmission Using Ultrasonic Sensor and Arduino Uno

Abstract

With the rapid development of current technology, the use of dispensers to fill water into the glass can be done automatically as a substitute for dispensers for filling water that is still manual. With the prototype method we can design or make automatic dispensers using ultrasonic sensors and Arduino Uno. this tool uses an arduino uno microcontroller as its main controller, an ultrasonic sensor as an input and as a measuring tool when the water is full or within specified limits, a relay as a power delivery to a water pump that will flow water from gallons to the measuring cup provided and buzzer as alarm if the water has finished filling. From the results of the design makes it easy for users because it is already automated in terms of filling and then the determined water dose.
