TEMPERATURE AND HUMIDITY MODULE
HF 3223 / HTF 3223
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.
MAIN FEATURES
G Size and connector type match existing humidity modules.
G Stable, linear proportional frequency output from 10 to 95% RH.
G Calibrated within +/- 5% RH @ 55% RH.
G Optional 10 K +/- 3% NTC temperature sensor (HTF 3223)
G Stable characteristics with temperature.
G High reliability and long term stability.

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.
NTC resistance in at temperature T in K
NTC resistance in at rated temperature in K
Temperature in K
B value,material-specific constant of the NTC thermistor
Base of natural logarithm (e =2.71828)
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 relation as given in tabulated form. The below table
has been experimentally determined with utmost accuracy for
temperature increments of 1 degree.
