Design of a measuring unit for smart agriculture
Kostelanská, Alžbeta ; Kubánek, David (oponent) ; Herencsár, Norbert (vedoucí práce)
The Master's thesis is dealing with the design of an intelligent measuring unit aimed at the field of smart agriculture. The proposed measuring unit is intended to provide automated measurements and monitoring of plant conditions utilizing electrical bioimpedance spectroscopy. In the theoretical part of the thesis, the concept of bioimpedance is introduced, the main focus is on the interpretation of its value in the context of agriculture. The practical part of the thesis is dealing with the design and implementation of a prototype impedance analyzer which utilizes an integrated analogue impedance interface. The output of the thesis is a prototype of the measuring unit and an interface for visualization of the measured data. The conclusion of the thesis is devoted to the evaluation of the results of the measurements, which have been conducted by the constructed prototype.
IoT WiFi soil moisture and temperature sensor
Kostelanská, Alžbeta ; Zeman, Václav (oponent) ; Škorpil, Vladislav (vedoucí práce)
Bachelor thesis addresses the subject of IoT WiFi soil moisture sensor and temperature sensor based on ESP32 platform. The primary focus of the design is on low power consumption of the device and secure communication. The theoretical part of the thesis describes selected types of sensors which can be used for the designed device. The ESP32 module and some of its features are also introduced. Lastly selected communication protocols which are suitable for IoT applications and can be used with WiFi peripheral are discussed. The practical part of the bachelor thesis deals with hardware design of the sensor device and implementation of this design. Low power consumption is implemented in hardware and in software solution. The focus is on independence of the device and secure communication and data protection. Lastly the concept of webserver used for storing and processing collected data on RaspberryPi platform and concept of sending the measured data to the end-user are introduced.
