Product Specification

HCT01 Humidity and Temperature Sensor Description
HCT01 humidity/temperature sensors combine high quality, long time approved thin-film sensor technology simple processability and the possibility of a cost-efficient integration into customer application.

The pre-adjusted capacitive E+E humidity sensorelement saves complicated and time-consuming humidity adjustment. Highly accurate thin-film elements are used for the temperature measurement – a must for precise dew point determination.

The DFN packaging guarantees maximum mechanical sensor protection and enables reflow soldering. A protective film on the surface of the humidity sensor ensures extensive protection against contamination like dust, salt or chemical deposit.


Depending on the individual application, accuracy requirements and existing interface electronics, different cost-saving evaluation circuitries are available. Do not hesitate to contact our specialists for further information and design-in support.
