Abstract: This manuscript presents a new approach to the use of Internet of Things technologies in a practical and significant way in the system of smart data loggers. The subject of research is the observation and control of the microclimate using Internet of Things technology and smart sensor nodes. It is known that working environments take into account the ambient parameters that influence the concentration at work so that efficiency is at the highest level. For this reason, the primary goal is to create an inexpensive smart system for storing data obtained by measuring different ambient parameters and controlling them without any human involvement. The proposed smart data logger system is based on the following steps: directly monitoring the environment, measuring and storing data, and then allowing the user to adjust the parameters and provide a more comfortable working environment. This research will present the design and implementation of the practical smart data logger system, which can be further expanded where such a realized system can form part of a smart faculty. The system is based on: a group of built-in sensors, a microcontroller with a peripheral interface (PIC) as a core and a server system and a wireless Internet using the Global System of Mobile Telecommunications (GSM) module with General Packet Radio Service (GPRS) as a communication protocol. There is also a smartphone application that allows the user to monitor and control the ambient parameters. It is possible to implement a smart faculty service, in which the realized smart data logger system could be implemented, which enables automatic control of ambient parameters at the faculty.
