Abstract

Aquaculture is a multibillion-dollar industry growing worldwide, especially in developing countries. This thesis focuses on a comprehensive study of off-grid fish farming in rural areas of Pakistan. A suitable site is selected for a fish farm. The solar PV system was designed and optimized for this fish farm on their annual load requirements, which are 100% renewable. Results demonstrated that the designed Solar PV system fulfilled the fish farm load smoothly and sufficiently throughout the year. Initial cost and maintenance are also estimated using HOMER Pro. Data were collected from the site survey and found there was not any system for water pumping system operations. The water pump operated manually through labor based on the visual determination of water level in ponds, Which increased production cost, electricity consumption, and wastewater. For this problem, Proposed a water pumping system automation and control using TinkerCAD. As a result, the system worked efficiently using an ultrasonic water level sensor and a low-cost motor with a microcontroller. The designed system works automatically when the water level drops to the threshold and stops. The major part of this thesis is designing and implementing an IoT-based real-time health monitoring system for the fish farm. Microcontroller Arduino Uno and Wi-Fi module ESP8266 used for the proposed system and designed a system to monitor the most critical metrics of the fish farm using an ultrasonic sensor temperature sensor, pH sensor, and dissolved oxygen sensor. ThingSpeak Cloud platform is used for data storage and display. Aquafarmers can access the fish farm health monitoring system through the web interface and phone App.
