Design and Implementation of Smart Aquarium
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryMany people use to keep fish in their houses and offices as a hobby as well as decoration purpose. Maintaining an aquarium needs attention and time but in this era, people are busy with their work. To make it easy and simple for the people, we are designing Smart Aquarium that will monitor and control various parameters of aquarium including water level, temperature, pH of the water, oxygen and feeds the fish on time.
The proposed system uses a microcontroller (Raspberry pi) to control the described parameters using sensors and actuators. For measurements, there are temperature, level and pH sensors while actuators include oxygen pump, heating rod and water pumps. The contaminated water pumped out of the aquarium will flow towards plants. At wanted time intervals, automatic fish feeder feeds the fish. The aquarium will be monitored using Camera on our IP login.
Project Objectives- To develop a reliable monitoring system for users by sensing the parameters and taking decisions on them.
- To develop a real-time aquarium monitoring system that gives information about the aquarium using Camera.
- To facilitate automatic fish feeding.
- To avoid the wastage of water by irrigating the plants.
- To make it more convenient and easier for the user by displaying all parameters.
- Sensors selection and Measurements: We have selected temperature and pH sensor to take measurements in water.
- The decision on Measurements: If the temperature and pH of water exceed the limits, the controller (Raspberry pi) will take decisions and make heater rod or water motors to be ON/OFF accordingly.
- Camera Monitoring: Camera will monitor the aquarium condition and will forward the picture to our IP page.
- Controller Selection: Raspberry bi is used as a controller having 40 GPIOs We have interfaced our controller using one wire and I2C communication protocol.
- Sensors Selection: The 1-wire DS18B20 temperature sensor will be submerged in the aquarium to sense the water temperature. Our pH sensor pH4502c with ADS1115 is interfaced using I2C communication protocol to measure the pH of water. Ultrasonic sensor HC-SR04 is used to measure the water level.
- Actuators selection: HW-1000 heating rod is selected to maintain the temperature of the aquarium to achieve the desired limit, oxygen pump to provide oxygen and Water pumps for in and outflow of water.
Figure 1 shows our proposed sequential block diagram of the project.

Benefits of the Project- Energy efficiency.
- Automation and smart devices.
- One-touch maintenance.
- More user-friendly.
- Human effort will be minimized.
- Maintain water cleanliness.
- Feeding at one click.
- Low cost.
- No wastage of water.
Software: We are using Python for Coding and are controlling our actuators (submersible heater, water inlet and outlet pumps) by sensing the temperature, pH and water level.
Hardware: The hardware will be our aquarium with sensors connected and measuring the variables of the aquarium.
Mechanical: Heater and water pump mechanically structured to heat the water and maintain water level to desired limits.
All the process will be monitored using Camera and will be displayed on our login IP page.
Given below is the final view of our project.
