Technologies Driving the Shift to Smart Farming: A Review

Abstract

As today's agriculture industry is facing numerous challenges, including climate changes, encroachment of the urban environment and lack of qualified farmers, there is a need for new practices to ensure sustainable agriculture and food supply. Consequently, there is an emphasis on upgrading the farming practices by shifting towards Smart Farming (SF) -utilizing advanced information and communication technologies to improve the quantity and quality of the crop with minimal labor interference. SF has gained lots of interest in recent years utilizing a variety of technological innovations in the field, which imposes a challenge on farmers and technology integrators to identify the suitable technologies and best practices for a particular application. This paper provides a survey of the most recent SF scientific literature to identify common practices toward technology integration, challenges, and solutions. The survey was conducted on 588 papers published on the IEEE database following Cochrane methods to ensure appropriate analysis and interpretation of results. The papers' contributions were analyzed to identify necessary technologies that constitute SF, and consequently, research themes were identified. The identified themes are sensors, communication, big data, actuators and machines, and data analysis. Besides presenting an in-depth analysis of each identified theme, the paper discusses integrating more than one technology in systems to achieve independency. The most common SF systems are remote monitoring, autonomous, and intelligent decision-making systems.

Smart Hydroponic Systems: Optimizing Nutrient Levels with IoT Connectivity

“…Communication protocols for hydroponics are discussed in various reviews, including [23][24], [29]. Microcontrollers and sensors play a crucial role in hydroponics and are considered in the literature, as showcased in [25][26][27][28]. Large greenhouses are increasingly adopting hydroponic farming methods, as highlighted in [30] The integration of artificial intelligence, machine learning, and IoT has helped the agricultural sector with predictions, accurate parameter measurements, and improved yields, as demonstrated in surveys [31].…”

Ion-Selective All-Solid-State Printed Sensors: A Systematic Review

“…potential, impedance, current). This class of sensors has proven to be very interesting due to the wide range of applications, ranging from healthcare [3] to agri-food smart applications [4] or environmental monitoring [5]. With these types of sensors, one of the most widespread applications rely on ions quantification within bio-fluids (sweat, plasma) to monitor human health in particular in term of hydration state, muscular exercise, and different types of diseases [6].…”

"Intelligent Firmament - An Overview on Crop Classification and Recommendation System Using Machine"

“…To guarantee suitable analysis and interpretation, the survey was carried out on 588 papers that were published on the IEEE database using Cochrane methodology. After analysing the contributions provided by the papers, research themes were determined in order to ascertain the technology needed to create science fiction [14] . Data analysis, actuators and machines, big data, sensors, and communication are the themes that have been found.…”
