Based on the rugged HTS2030SMD humidity sensor, HTF3130 is a dedicated humidity and
temperature transducer designed for OEM applications where a reliable and accurate measurement is
needed. It features a very small size for easy, cost-effective mechanical mounting. Direct interface
with a micro-controller is made possible with the module’s linear frequency output.

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.
2For 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.
