Pre-adjusted, Capacitive Humidity Sensor


The HCT01 humidity and temperature sensor combines high-quality, long-term tested thin-film sensor technology with the easiest workability and a cost-efficient integration of the humidity sensor into your application.

HCY01 humidity sensor

The humidity sensor comes pre-adjusted from the factory thus making a time-consuming humidity adjustment unnecessary. The temperature measurement occurs using a highly precise thin-film element, a must for the exact determination of a dewpoint.

The DFN housing of the humidity sensor ensures maximum mechanical sensor protection and facilitates the processing using standard reflow soldering process. A protective film applied to the active humidity sensor surface ensures a protection against contamination such as dust, salt or chemical pollution.
Depending on the accuracy requirements and available evaluation electronics, different cost-effective evaluation circuitry is available for the humidity sensor – our specialists will be glad to assist you.
