Abstract

DESIGN AND CONSTRUCTION OF AN AUTOMATED LIQUID DISPENSER

Arnaldo Villalon, Jacob Godino* and Noel Pacayra

ABSTRACT

This study centers on the design and fabrication of an Automated Liquid Dispenser which can help prevent spreading of the virus. This device is useful especially in hand washing. The user of this device will limit the contact while using this device. In order to construct the Automated Liquid Dispenser, it would be appropriate to study the material and to determine the design suited for the device. Automated Liquid Dispenser uses IR transmitter and IR Receiver or Photodiode as a sensor switch. It has Op Amp integrated circuit for switching and amplifying the input current and voltage. DC motor is used to dispense liquid in the Automated Liquid Dispenser.
