The article develops a temperature and relative humidity control system for automating cooling systems of smart buildings by applying fuzzy logic rules. Temperature and relative humidity are considered as input parameters, the AC mode is considered as an output parameter. A model device is presented where the system receives input data from a temperature and humidity sensor (DHT11) using an Arduino microcontroller, then the received data is analyzed by a control system based on fuzzy logic. The action of the proposed system is considered, where it automatically controls cooling devices when the temperature changes from 0 to 50 ℃ and relative humidity from 0% to 90%. The optimal method of transmitting system data using the ESP8266-12E Node MCU Wi-Fi microcontroller for monitoring and controlling parameters in real time online via the Internet of Things is considered. The results obtained show that the proposed system can be practically applied in smart buildings, provide early warning to the user about changes in remote parameters in real time and at the same time start the cooling system to adapt the temperature regime to the desired one.
