This paper is devoted to the research of the important issue of increasing the efficiency and optimization of microclimate management processes in residential premises. The purpose of this study is to create an automated system for accurate setting and control of the main parameters of the microclimate in the room, which will make it possible to increase comfort and energy efficiency. To achieve the task, the Arduino platform is used, which is an open hardware and software system with a wide range of opportunities for developing embedded systems.


This article presents the technology of 3D design of fire detector body parts using the CAx system. During the 3D design of the components of the fire detector, its design has been improved, and its operation is ensured on the basis of the Arduinomini board. The production of the lower cover of the fire detector for the Arduinomini board is realized with the help of a 3D printer. At the same time, a thermal analysis was carried out in the CAx Fusion 360 system of the improved fire detector design.

Device for controlling parameters of accumulator batteries and the corresponding direct current network

Mobile devices for information, control and telemetry systems are powered by mobile generators through AC to DC converters, by batteries or, if possible, directly by solar panels. Solar panels typically work in a system that involves the usage of batteries to keep the systems running when the solar panels are not working or not providing enough power. The batteries can be recharged from the panels themselves if the solar panels have sufficient power or from an external direct current source.

Experimental System and Software: Two-dimensional Return of the Platform to the Sound Source

We created a system, debugged it, and conducted experimental studies of the two-dimensional rotation of the supporting platform (with a camera, and a light source.) on the source of sound waves. The system was assembled based on two SYNCO Mic-M3 cardioid condenser microphones and an Alesis IO-4 sound card. We wrote original software for analyzing and transmitting the result of processing harmonic acoustic signals for the response of the Arduino Uno control board. The rotation of the 2D platform is caused by two MG995 servos controlled by this microcontroller.
