Introduction. The study of the parameters of the clothing space is extremely important in the development of seasonal clothing for the military, police, athletes, etc.
Problem Statement. The use of “smart” textiles capable of responding to changes in the environment, adapting to it by integrating functional capabilities into the textile structure, deserves attention. Person’s feeling and emotional response are accompanied by electrical, thermal, chemical or other changes in the human body, which can be recorded by electronic devices and used to monitor the comfort of clothing.
Purpose. The purpose is to develop a functional system for monitoring the interlayer space of clothing given the temperature and relative humidity and for creating a prototype remote control system for clothing.
Materials and Methods. Sensors (a microcontroller with a battery, radio modules, temperature and relative humidity sensors) placed in the knitted structure of the T-shirt, on certain parts of the human body have been used. Atmega328 microcontroller equipped with 18650 batteries has been employed to detect the temperature and the relative humidity in the interlayer space of the clothing with the help of DS18B20 temperature sensors and DHT22 humidity sensors. The HC-12 radio module has been used for transmitting the data from the microcontroller to the target device. The data have been processed by a special program with the use of the Serial, NumPy, Matplotlib, and Drawnow libraries.
Results. The system for remotely monitoring changes in the internal microclimate within the airspace between layers of diff erent clothing materials has been developed. The relationship between the average temperature and the relative humidity in the interlayer clothing space has been determined and are equal to ~26 0C and 29.8%, respectively, after exposure to an outdoor temperature of –10 0C.
Conclusions. The obtained results can be used to improve existing and to develop new items of clothing with increased comfort.
