B7.2 - Low-Cost Smart Self-Adaptive Humidity Sensors with Parametric Adaptation

Sergey Yurish
A low cost humidity and temperature smart self-adaptive sensors systems with parametric adaptation is described in the paper. The system is based on dedicated humidity and temperature transducer HTF3130 and Universal Sensors and Transducers Interface (USTI) integrated circuit, especially designed for such applications. The transducer consists of rugged HTS2030SMD humidity sensor and NTC temperature sensor. The USTI directly converts frequency proportional to the humidity (10 %RH … 95 %RH) and resistance proportional to the temperature...
