Biofloc System Monitoring and Control
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryIn our project, we are designing a monitoring and control system that is useful for measuring the quality of water in an aquarium and ammonia level as well as dissolved oxygen, pH level and temperature of water for fish cultivation. The project involves sensors like Ammonia Sensor, pH sensor, Dissolved Oxygen (DO) sensor, and temperature sensor which will connect to Raspberry pi Board. The device utilize the internet to process works automatically.
In conventional ponds the Dissolved oxygen, pH level and ammonia level varies with density of the fisheries, so when the oxygen in the water reduces it make the fisheries less likely to survive in such low oxygen level. The DO sensor will detect this and switches on the air pump or aerators which then balance level of the oxygen in water. And if pH level of water changes from 7, water will becomes either acidic or basic and that is not good for fisheries. In that case pH sensor will detect pH level so that we can take particular measures to achieve the pH to 7. Similarly we can also maintain temperature of water by temperature sensor and ammonia level using ammonia sensor.
The objectives of our project are
- To reduce the water usage
- To reduce the cost of feed
- To increase the growth of fish
- To control the parameters(Ammonia Concentration, Dissolved Oxygen Concentration, Temperature & pH )
- Use of modern tools to reduce the work load
- Automation in the field using Raspberry pi
- Smart surveillance through live streaming using camera.
In our project we use sensors to measure the concentration levels, like to measure ammonia concentration, dissolved oxygen, pH and temperature. We also use an advanced micro controller called Raspberry pi to automatically control whole process. For example if the concentration level of ammonia decrease from certain level the air pump will turn on and keep on running till the level reaches to optimal value. We also use a camera for surveillance of whole area of production. This surveillance system will keep the owner updated about the situation in area. We are also going to use a mobile application to control these task. This will reduce the labor force and save more profit. To deal with the energy supply instead of commercial electricity we are planning to produce our own by using solar power which will also reduce the cost of electricity and we can have cheap supply of electricity. For night time when there is no sunlight we can use batteries as our backup.
Benefits of the ProjectOur system is more efficient then the chemical testing, in this project we will use sensors to test the concentration and limit the values to its optimal whenever the value surpass the optimal the air pump turns ON and full-fill the deficiency. But it also have a drawback that is it do not give us the solution for power consumption and supply which is also a major issue. Because in our country due to the lack of electricity production, load shedding is a big issue. This will be a problem because we have to manage the air supply timely if not the fish will die in no time.
To deal with the energy crises we planned to get some useful energy source which will supply continuous supply of electricity. Solar energy is good choice in that terms because it is cheaper and cleanest form of energy that we can have. In night time in the absence of sunlight we can use batteries as an alternative source for back up.
We also search for a system in which we can control whole process from a smartphone application. Through this app we can control the supply of air timely by turning the air pump ON/OFF. Through this application we can also get live stream to monitor whole area by using a camera.
