Development of a Tray-Separated Microbiological Incubator by Means of Electronic Components and Testing Its Performance

摘要

Within the realm of genetics, bioengineering and especially microbiology, it is often necessary to develop and grow a certain type of microbial culture for purposes of investigating certain microbiological phenomena or conducting a research. In order to perform the process of incubation, it is required to maintain a constant temperature for the time frame within the range of 24-48 h, depending on the type of bacteria under investigation. The device which enables us to grow such group of microorganisms is called a microbiological incubator. Two crucial parts in the microbiological incubator are heater and temperature sensor. Usually, such incubators have one chamber, whose temperature is controlled by a microcontroller. This project aims to improve the functionality of regular microbiological incubators by designing one which will have two separately controlled chambers and therefore be more functional than a conventional one. The incubator will be controlled with NodeMCU platform with integrated Wi-Fi module, so it will have IoT prefix, which basically means that one will be able to control it and to obtain certain data from it via the internet.
