ceramics. Extensive research was conducted to examine these sensors. The results indicate that the temperature-sensitive thick-film elements exhibit sensitivity within the temperature range of 298 to 358 K, while the humidity-sensitive sensors demonstrate sensitivity from 30% to 98% during absorption-desorption cycles. These fabricated sensors were implemented in a microprocessor information measuring system, primarily focusing on environmental monitoring and control.
