Surface-mounted temperature-humidity sensor with active and passive output

Application/Description

For the exact measurement of the relative humidity and temperature of air and other non-aggressive gases, the measured variable is converted into a standard signal. It is used as a surface-mounted sensor in refrigeration, air conditioning and clean room technology in living rooms, offices, hotels, etc. A digital, long-term stable sensor is used as a measuring element for humidity measurement. The temperature can be specified either actively or passively.
