In this project was shown approaches to the implementation of a weather station for monitoring the microclimate in the room on Arduino platform. Considered a platform for project development and software environment. The virtual scheme of the weather station is modeled. The main functions of the components are described and their connection to the microcontroller is shown. The process of firmware of the microcontroller is considered. The algorithm of system operation is described. A functional electrical diagram were also constructed.

The electron energy state, magnetic and transport characteristics of thermometric materials HfNi1-xCoxSn were investigated in the T = 80 ¸ 400 K temperature range and at charge carriers concentration from Co » 9,5×1019 NA см-3 ( x = 0,005 )÷ 5,7 ×1021 см-3 ( x = 0,30 ) and H £ 10 kGs. The material HfNi1-xCoxSn is sensitive to the temperature change and could be used as the basis for the sensitive thermoelectric devices. We investigated the crystal structure, electron density of states (DOS) and the kinetic and energy characteristics of n-HfNiSn heavily doped with the Co impurity.
