TEMPERATURE AND HUMIDITY MODULE
Based on the rugged HS1101 humidity sensor, HF 3223 / HTF 3223 is a dedicated humidity and
temperature transducer designed for OEM applications where a reliable and accurate measurement is
needed. It features a miniature connector for easy, cost-effective mechanical mounting. Direct interface
with a micro-controller is made possible with the module’s linear frequency output.

Typical temperature output
Depending on the needed temperature measurement range
and associated accuracy, we suggest two methods to access to
the NTC resistance values.
1
The actual characteristic of an NTC thermistor can, however, only
be roughly described by the exponential relation,as the material
parame ter B in reality also depends on temperature. So this
approach is only suitable for describing a restricted range around
the rated temperature or resistance with sufficient accuracy.

2 For practical applications a more precise description of the real
R/T curve may be required. Either more complicated approaches (e.g
the Steinhart-Hart equation) are used or the resistance/

temperature increments of 1 degree.
