Czech University of Life Sciences, Faculty of Engineering: Digital twin of a smart garden and IoT in precision agriculture

Smart garden and demonstration atrium as a digital twin

At our exhibition stand, we present the concept of a smart garden and a demonstration laboratory atrium integrating modern agronomy, renewable energy sources, and advanced elements of automation and the IoT. The exhibition focuses on the presentation of precision agriculture principles and autonomous measurement and control systems through the use of virtual reality (VR) in combination with selected physical technological components.

The real demonstration atrium, which serves as an experimental and educational platform, is presented at the exhibition indirectly through a digital twin implemented in VR and via a web-based presentation. Visitors can virtually explore the atrium, become familiar with its spatial arrangement, and view current measured values of individual parameters directly in the context of specific cultivation areas, sensors, and technological units. The digital twin thus enables a clear and intuitive demonstration of the operation of the entire system.

The virtual model represents a smart garden integrating crop cultivation with agrivoltaics, complemented by an environmental monitoring system. The system also includes measurements of meteorological variables from a weather station, such as air temperature and humidity, as well as solar radiation intensity, together with detailed measurements directly within individual planting beds. These include sensors for soil moisture, temperature, and nutrient concentration, with the collected data serving as input for irrigation and fertilisation control.

The control of technological processes is based on the continuous acquisition of data from IoT devices, their processing in a central control unit, and storage in a database. The system is designed as an off-grid solution with its own electrical energy management. Energy is generated by photovoltaic panels, stored in a battery system, and distributed among individual technologies according to current operational demands.

Autonomous measurement and modern technologies in precision agriculture

In addition to the virtual presentation, selected autonomous sensing and measurement systems used in the real atrium will also be exhibited at the stand. These include, for example, wireless devices for measuring soil moisture, temperature, and other soil properties, together with demonstrations of their solar-based power supply and the principles of long-term autonomous operation.

The aim of the exhibition is to clearly demonstrate the integration of physical sensing devices, IoT communication infrastructure, data processing, and modern visualisation tools. The presented solutions are the result of student-led projects and illustrate the practical application of modern technologies in precision agriculture, sustainable energy systems, and digital twins.

Study program focused on IoT and automation in agri-food

The Department of Electrical Engineering and Automation at the Faculty of Engineering, Czech University of Life Sciences Prague is responsible for both the bachelor’s and follow-up master’s degree programmes Information and control technology in the agro-food complex.

The study programme is focused on the integration of information technologies with automation and control engineering, particularly in the context of contemporary approaches based on the Internet of Things (IoT) concept. The department’s educational activities cover sensor design and implementation, operating principles and properties of electrical components and circuits, measurement systems and their associated errors, as well as automation and control systems, including control and applications of power engineering.

The department’s research activities are oriented towards the development, deployment, and application of automation and control technologies, the implementation of measurement systems, and modelling using DEM and FEM methods, including the development of digital twins.
