ceramics were fabricated and studied. It is shown that temperature-sensitive thick-film sensors possess sensitivity in the region of 298...358 K and humidity-sensitive sensors are sensitive in the region of 30...98 %. Designed sensors were used in the portable system realized on Arduino for monitoring and control of microclimate parameters. Obtained system were tested using Android application.
