This bachelor thesis presents an example and design of a smart greenhouse for small agricultural production with a system of components monitoring conditions in the greenhouse. The parameters that influence the growth of plants such as air temperature, air humidity, soil moisture, the amount of sunlight and the amount of carbon dioxide are listed. Their positive and negative effects on plants grown in the greenhouse are elaborated in detail. Temperature and humidity sensor, soil moisture sensor, fan, Arduino board, stepper motor, light emitting diodes and other necessary components were also explained. The components have been selected so that it is possible to realize such project in a do-it-yourself (DIY) form without large costs. The thesis continues by giving suggestions for construction of the greenhouse itself and the way to integrate the proposed components with the example of the computer program. After the creation and integration of the proposed components, the validation of the fully constructed smart greenhouse was carried out. Validation positively confirmed the proposed and implemented model of a smart greenhouse for small agricultural production.
