Maintaining fish in an aquarium is not just a hobby, but also a means of relaxation and beauty in our living space. However, one challenge that is often faced by the owners of aquarium is to ensure that the fish get feed according to the right time and amount, especially for those who have a high activity. To overcome this problem, the design of automatic fish feeding systems using the Arduino Uno microcontroller integrated with Android applications is an interesting solution. The integration of technology and aquarium management has become a growing trend in recent years, and this project aims to contribute to this movement by providing a convenient and efficient way to feed fish.

System Concepts and Design

This system is designed to allow users to regulate the amount of feed given to fish and get feedback when the feeding process is complete. By utilizing Arduino Uno as the main controller, this system can automate the whole process. The use of Arduino Uno as the brain of the system allows for precise control and regulation of the feeding process, ensuring that the fish receive the right amount of food at the right time. In its implementation, this tool is equipped with an ultrasonic sensor that serves to detect the availability of feed in the feed container. This sensor will measure the distance between the feed surface and the sensor and send the data through the ESP8266 WiFi module to the user device, such as an Android smartphone. Users will be able to see the status of the availability of feed in real-time, so they can plan fish food supplies better.

System Work Mechanism

This system relies on several main components:

Arduino Uno: Functioning as the brain of the system, regulating all operations of instructions received through the application. The Arduino Uno microcontroller is a popular choice for IoT projects due to its ease of use and flexibility.
Ultrasonic sensor: Measuring the height of the remaining feed in the container, providing important data to determine when feed must be added. The ultrasonic sensor uses high-frequency sound waves to measure the distance between the sensor and the feed surface.
ESP8266 WiFi Module: Continuing data from the sensor to the Android application and also receives commands from the user to feed fish. The ESP8266 WiFi module allows for seamless communication between the Arduino Uno and the Android application.
Android Application: Providing users with a user-friendly interface to control and monitor the feeding process. The Android application allows users to set feeding schedules, monitor feed levels, and receive notifications when the feeding process is complete.

Benefits of Automatic Feeding System

This automatic fish feeding system offers a variety of significant benefits for fish owners:

Time efficiency: Users no longer need to worry about feeding fish every day. All can be done only with one setting through the application. The automation of the feeding process saves users time and effort, allowing them to focus on other aspects of aquarium management.
Appropriate feeding: With the regulation of the right amount of feed, fish can get nutrition as needed without the risk of excess feed that can pollute water. The precise control of the feeding process ensures that the fish receive the right amount of food, promoting optimal health and well-being.
Ease of monitoring: Through the application, users can monitor feed status in real-time and get notification when the food feeding process is complete. The real-time monitoring feature allows users to stay on top of the feeding process, ensuring that their fish receive the care they need.

System Implementation

The system implementation involves several steps:

Hardware setup: The Arduino Uno, ultrasonic sensor, and ESP8266 WiFi module are connected to the feed container and the Android device.
Software development: The Android application is developed to communicate with the Arduino Uno and monitor the feed levels.
Testing and validation: The system is tested and validated to ensure that it functions as intended.

Conclusion

With the automatic fish feeding system using Arduino Uno which is controlled by an Android smartphone, the activity of raising fish is more practical and fun. This tool not only helps manage time better but also maintains the health of fish optimally. People can enjoy the beauty of aquariums without worrying about the needs of fish feed that must be considered at any time. This technological innovation shows that progress in the field of technology can facilitate daily activities, including in the hobby of raising fish.

Future Work

Future work on this project can include:

Improving the accuracy of the ultrasonic sensor: To ensure that the sensor provides accurate readings, even in different lighting conditions.
Developing a more user-friendly interface: To make it easier for users to set up and monitor the feeding process.
Integrating with other aquarium management systems: To provide a more comprehensive and integrated solution for aquarium management.
