Sensor for long-term control of food quality
Navara, Róbert ; Búran, Martin (referee) ; Adámek, Martin (advisor)
This final thesis focuses on the problems related to the lifespan of food and it’s monitoring. The first chapter is focused on the food businesses and on the creation of system HACCP which those businesses need to implement. Next chapter talks about factors which have the biggest impact on the lifespan of meat. The chapter about technologies used for monitoring of health safety of food talks about most used and most viable sensing tags used for this purpose. The following chapter describes microcontroller ESP32, it’s pros, it’s cons and it’s programmability. The practical part revolves around the realization of a printed circuit board, fitted with a microcontroler ESP32, a relative humidity and temperature sensor HDC1080 and an ammonia sensor MiCS-6814, which as a whole along with designed firmware and software work as a sensor tag, which is capable of measuring, saving and exporting data based on a configuration of an user.

Innovation of device for mealworms breeding
Dvorský, Adam ; Búran, Martin (referee) ; Adámek, Martin (advisor)
The task of the work was to get familiar to the reader with the possibilities and conditions of edible insect breeding in the Czech Republic, focusing on a selected species of darkling beetle (Tenebrio molitor). Design optimization of breeding conditions for different stages of breeding, with the possibility of accelerating breeding. Another part of the work was to get acquainted with the properties of the microcontroller series Espressif ESP32 and its use in the areas of simple product management. From these identified conditions, a breeding station was designed and gradually implemented in the second half of the work, which was controlled by this microcontroller company Espressif ESP32. The work describes the proposed components for measuring and regulating breeding conditions with a focus on temperature, humidity, food and fluid dosing. The penultimate chapter mentions experimental measurements of regulated conditions with evaluation of measured data. The conclusion is the evaluation of the solution and its other possibilities.

Device for measurement and regulation of edible insect breeding conditions
Dvorský, Adam ; Búran, Martin (referee) ; Adámek, Martin (advisor)
This work focuses on the design and realization of a measuring and regulatory system for successful breeding of edible insects with a focus on the mealworm (Tenebrio molitor). For the correct setting of the system, the first part of the work is detected and described the general conditions of insect breeding. The description is mainly focused on the mealworm, its development and basic breeding conditions (temperature, humidity, etc.). This information is further used for the development of breeding equipment, the basic concept of which is further established at work. The device is controlled by espressif's ESP32 microcontroller. The work acquaints with its programming and the connection and programming of basic components for the proposed system. Experimental measurements verify the functionality of measurements and regulation in the breeding box. The regulation is accurate to tenths to hundredths of ° C.Last but not least, the design is compared with existing devices.
