The work presents and substantiates the design and operation mode of the measuring complex for determining the effectiveness of technical means of fire extinguishing with finely sprayed water. The measuring complex consists of 5 integrated humidity and temperature sensors, an information processing unit with a memory card and a power supply unit. The sensors are connected to the information processing unit (display driver board and sd card slot), which allows you to process and record the received information on a memory card. The measuring complex is powered by a laptop or power bank connected to the information processing unit. Processing of measurement results is carried out using computing equipment (laptop, tablet, etc.) with the pre-installed WPS Office or Microsoft Office program. Information is read from the sensors every second, and the total measurement time is limited by the memory card. The error of humidity and temperature measurements by the developed complex is determined based on the measurement error of the sensors used. For measurements, a scheme is proposed where the sensors are placed at different heights and distances from the center of the internal fire. Due to the use of the measuring complex, temperature and humidity indicators are measured when determining the effectiveness of modern technical means of fire extinguishing with fine spray, which ensure minimal consumption of extinguishing agent, mobility and have a simple design. By evaluating the efficiency of technical means of fire extinguishing with finely sprayed water, their scope of use is determined, and due to their mobility and autonomy, the level of safety of the personnel of fire and rescue units during fire extinguishing, including in the conditions of combat operations, will be increased.
