Optimisation of small-scale aquaponics systems using artificial intelligence and the IoT: Current status, challenges, and opportunities

Environment changes, water scarcity, soil depletion, and urbanisation are making it harder to produce food using traditional methods in various regions and countries. Aquaponics is emerging as a sustainable food production system that produces fish and plants in a closed-loop system. Aquaponics is not dependent on soil or external environmental factors. It uses fish waste to fertilise plants and can save up to 90–95% water. Aquaponics is an innovative system for growing food and is expected to be very promising, but it has its challenges. It is a complex ecosystem that requires multidisciplinary knowledge, proper monitoring of all crucial parameters, and high maintenance and initial investment costs to build the system. Artificial intelligence (AI) and the Internet of Things (IoT) are key technologies that can overcome these challenges. Numerous recent studies focus on the use of AI and the IoT to automate the process, improve efficiency and reliability, provide better management, and reduce operating costs. However, these studies often focus on limited aspects of the system, each considering different domains and parameters of the aquaponics system. This paper aims to consolidate the existing work, identify the state-of-the-art use of the IoT and AI, explore the key parameters affecting growth, analyse the sensing and communication technologies employed, highlight the research gaps in this field, and suggest future research directions. Based on the reviewed research, energy efficiency and economic viability were found to be a major bottleneck of current systems. Moreover, inconsistencies in sensor selection, lack of publicly available data, and the reproducibility of existing work were common issues among the studies

Fresh Bytes - Connected Hydroponics for Small-Scale Growing

Many users are now transitioning to small-scale hydroponics and aquaponics at home.

There are sensors for these various components but they are either aimed at commercial production or are un-automated. Fresh Bytes is a microcomputer with sensors to detect all of these unseen components in a hydroponic system. A prototype of this microcomputer is produced along with CAD plans for more professional versions of it. The sensors are verified and future development is contemplated

Fuzzy logic-based Control System to maintain pH in aquaponic

One of the important things in an aquaponic system is to keep the pH value of the water stable, so a system is needed to maintain the stability of the pH value. This paper describes the design of a pH control system in an aquaponic system based on fuzzy logic control. The system was developed using 2 pH sensors, a pH A sensor placed in the aquarium and a pH B sensor placed in hydroponics. The system also used 2 motor pumps, the first pump aimed to increase the pH value (pH up), and the second pump aimed to lower the pH value (pH down). In order to set the addition or reduction of pH to be more stable, a fuzzy logic algorithm was implemented to control the length of time the pump motor works. Testing the response system of the acid water to reach the set point took 11 seconds, the delay time td was 4 seconds, the rise time tr was 3 seconds. However, in alkaline water, it reached the set-point for 11 seconds, the delay time td was 3 seconds, the rise time tr was 2 seconds, and both occurred without overshoot

Implementing PID Control on Arduino Uno for Air Temperature Optimization

This research investigates the precise regulation of liquid filling in tanks, specifically focusing on water storage systems. It employs the Proportional-Integral-Derivative (PID) control method in conjunction with an HC-SR04 ultrasonic sensor and an Arduino Uno microcontroller. Given the paramount importance of water as a resource, accurate management of its storage is of utmost significance. The PID control method, known for its rapid responsiveness, minimal overshoot, and robust stability, effectively facilitates this task. Integrating the ultrasonic sensor and microcontroller further augments the precision of water level regulation. The article expounds upon the foundational principles of the PID control method and elucidates its application in the context of liquid tank filling. It offers a comprehensive insight into the hardware configuration, encompassing pivotal components such as the Arduino Uno microcontroller, HC-SR04 ultrasonic sensor, and the L298 driver responsible for water pump control. The experimental approach is meticulous, presenting results from tests involving the Proportional Controller, Proportional Integral (PI) Controller, and Proportional Integral Derivative (PID) Controller. These tests rigorously analyze the impact of varying Proportional Gain (Kp), Integral Gain (Ki), and Derivative Gain (Kd) parameters on crucial performance metrics such as response time, overshoot, and steady-state error. The findings underscore the critical importance of an optimal parameter configuration, emphasizing the delicate equilibrium between response speed, precision, and error minimization. This research significantly advances PID control implementation in liquid tank filling, offering insights that pave the way for developing more efficient liquid management systems across various sectors. The identified optimal parameter configuration is Kp = 5.0, Ki = 0.3, and Kd = 0.2

Use of Industry 4.0 technologies to reduce and valorize seafood waste and by-products: a narrative review on current knowledge

Fish and other seafood products represent a valuable source of many nutrients and micronutrients for the human diet and contribute significantly to global food security. However, considerable amounts of seafood waste and by-products are generated along the seafood value and supply chain, from the sea to the consumer table, causing severe environmental damage and significant economic loss. Therefore, innovative solutions and alternative approaches are urgently needed to ensure a better management of seafood discards and mitigate their economic and environmental burdens. The use of emerging technologies, including the fourth industrial revolution (Industry 4.0) innovations (such as Artificial Intelligence, Big Data, smart sensors, and the Internet of Things, and other advanced technologies) to reduce and valorize seafood waste and by-products could be a promising strategy to enhance blue economy and food sustainability around the globe. This narrative review focuses on the issues and risks associated with the underutilization of waste and by-products resulting from fisheries and other seafood industries. Particularly, recent technological advances and digital tools being harnessed for the prevention and valorization of these natural invaluable resources are highlighted

Financial viability of biomass produced in small-scale, low-cost aquaponic system in Ndwedwe.

Masters Degree. University of KwaZulu-Natal, DurbanThis study sought to determine the financial viability of small-scale, low-cost aquaponic systems in KwaZulu-Natal, particularly a small-scale, low-cost aquaponic system based in a rural homestead in Ndwedwe. The objectives of the study were to ascertain the financial viability of biomass yield (both fish and plants) in a small-scale, low-cost aquaponic system and to determine factors that affect the biomass output of a small-scale, low-cost aquaponic system. Aquaponics possesses the potential for food security and local economic development, because in aquaponics two enterprises (fish and vegetables) could be developed. However, aquaponics is an emerging practice in South Africa that possesses the potential of creating employment and ensuring household food security. The conventional methods of producing food have been criticised for producing toxic runoff which has had cumulative pollution effects. These effects include; the toxins from artificial fertilizers seeping into water bodies where people and marine life consume the intoxicated water. Conventional farming methods also increase soil run- off which depletes the soil reserves needed for sustainable farming practices. Aquaponics provides an alternative, sustainable method of farming which does not pose a threat to any ecosystems. On a global scale, it is evident that there is a need for innovative means of food production to address food and nutrition insecurity and the social ills that come with it such as poverty. Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs. Food and nutrition security are measured by four pillars, namely; access, availability, utilization and stability. These four pillars are determinants of food security, they measure whether people have sufficient access to safe and healthy food, and they are the standard by which food and nutrition security is determined. Access, availability, utilization and stability in food security is influenced by numerous factors such as politics, economic stability, location and dietary preferences. Aquaponics could enhance food sovereignty for both food and nutrition security, if implemented in communities, thereby serving all food security pillars
