The article presents the results of the study of the ventilation device. A system of automatic control of the process of regulating air exchange in a residential area has been developed, which allows you to control an element of the actuator, which increases the productivity and efficiency of the ventilation device. An automated module of the process of regulating air exchange in residential buildings has been developed, designed to control the regulation of air exchange and its determination in residential buildings in different periods of the year. The software module implements recalculation of the main heat and humidity parameters of the air.

The results of an experimental study of the process of laying asphalt mix with automation components of the technology of non-destructive continuous compaction control in the field of road construction are presented. The research was carried out in order to obtain real data for the task of creating a quality control system for compacting road materials in real time. During the study, the operating parameters of the paver were measured (velocity of movement, the frequency of impacts of the tamper, the frequency of vibration of the plate), the temperature of the compacted asphalt mixture, the thickness of the pavement layer, the vertical acceleration of the vibrating plate. The study used asphalt concrete mix type A grade I according to GOST 9128-2013. The operating parameters varied: the frequency of impacts of the tamper, the frequency of vibration of the plate. The acceleration of the vibrating plate was determined using a digital accelerometer with wireless signal transmission via Bluetooth to a smartphone with the Android operating system. The paper obtained the values of dimensionless complexes, the index of compaction of asphalt concrete mixture - the peak factor characterizing the change in the quality of compaction of asphalt concrete mixture.
