1. IoT ENABLED AUTOMATIC AUQUAPONICS SYSTEMS

2. INTRODUCTION Aquaponics refers to the combination of any conventional aquaculture system with hydroponics in a single symbiotic environment. In this system, ammonia rich fish wastes from the aquaculture tanks are pumped to the hydroponic beds. These fish wastes are converted into organic fertilizers needed for growing plants. In return, the plant roots filters and treats the water for habitation of the fishes, which is then recycled back into the aquaculture tanks

4. OBJECTIVES To monitor the system using mobile phone application and thereby reducing the barricade of human involvement in feeding ,filtering and air pumping in domesticated fishery system. To make this system a standalone device, by controlling entities such as motor pump, valves and feeder. To continuously monitor pH, temperature and turbidity of water using mobile phone and to ensure stable habitat of fish life and plants.

7. HARDWARE COMPONENTS pH Sensor Tolerable pH range is between 6-7. Excretions by fish causes fluctuations in pH, normally water turns basic in nature. To counterbalance, required amount of water is drained from the fish tank and fresh water enters from the main tank. Turbidity Sensor The turbidity of water in the fish tank increases due to fish waste depending on its size and composition. Turbidity sensor monitors the degree of turbidity. pH sensor module

8. Temperature Sensor The desired temperature for stable aquatic life ranges from 20 to 30 degree celcius. The sensor continuously acquires temperature values and whenever it goes beyond the range , water drains from the fish tank and freshwater enters from the main tank so as to nullify the effective temperature change.

9. Magnetic float switches It consists of two logic states; logic zero and logic one. When water level is higher than preset value its logic one else its logic zero. Motors The system consists of a motor pump, aerator pump and valves. All can be driven from the 12v line of solar panel installed. Fish Feeder Fish feeder consists of a gear motor and a funnel for uniform distribution. Quantity of food and number of times of distribution can be preset. Fish Feeder Layout

10. Online and offline communication There are two modes of monitoring ; online and offline . A NodeMCU is used for online monitoring. WiFi module in it connects to a database through which sensor controlling takes place. In offline monitoring a hotspot is created through the WiFi module and through this hotspot the system is connected and controlled .This can be easily monitored using the android application created. NodeMCU

11. CONC L USION Automation of aquaponics system can be effectively done using IoT. The system enables complete control and analysis using mobile application achieving all the standards of a standalone device. Data collected via sensors and stored in cloud database and monitored and controlled by microcontroller makes the system an efficient one. Aquaponics system being a source of balanced food production system which requires very less space and very less human efforts can be implemented in the terrace of houses. It is less time consuming and attention seeking. The only action required is to monitor using a mobile phone. Hence automating this system has a great potential to evolve as a game changer.
