ABSTRACT

Feeding fish in the aquarium can be done automatically using amicrocontroller. The microcontroller used in this project is nodeMCU. Thisproject uses some of the devices that are nodeMCU, HC-SR04 sensors, amicro servo SG90,a micro SD module included micro sd memory, male-famale cable, and a breadboard. The working of this project is thenodeMCU will read the time.txt and the alarm.txt in the micro SD. Thetime.txt used to set the time. The alarm.txt used to set the schedule toopen and to close the door of fish feed can. This project uses HC-SR04 tomeasure the volume of fish feed and the water level in aquarium. Tomontoring the fish feed can and the water level can be done with asmartphone and computer. The volume of fish feed can and the waterlevel will be sent to IoT server (www.thingspeak.com) and will be saved intxt file format.

Keywords: NodeMCU, HC-SR04 Sensor, IOT, Automatically FeedingFish.

PREFACE

First of all I would like to thank God because it can complete this

project. This project has the title “Automatically Feeding Fish using IoT

System.

The final project report consists of 6 chapters. The first chapter

describes the background problems, the scope, and the objectives of this

project. Chapter two contains a difference of this project from the previous

project. In chapter three discusses the steps in making this project.

Chapter four contains analysis and design for this project using flowchart

and schematic design. Chapter five discusses the implementation and

testing of this project. Then the last chapter six contains of the conclusions

from the writer and the project forward.
