Application Note
Humidity Module
HYT
1. HYT 271
Mechanically robust, chemical resistant and dew
formation resistant, the digital humidity sensor with
only 10.2 mm x 5.1 mm x 1.8 mm size offers the
widest application window and an optimal price
performance ratio. Precisely calibrated, the HYT 271
delivers an accuracy of ±1.8 % RH and ±0.2 °C - ideal
for sophisticated mass applications, industrial handheld
devices and precise humidity transmitters. Like all
representatives of the HYT family, the sensor combines
the advantages of a precise, capacitive polymer humidity
sensor with the high integration density and functionality
of an ASIC. The signal processing integrated in the sensor
completely processes the measured data and directly
delivers the physical parameters of relative humidity and
temperature over the I²C compatible interface as digital
values.
The module is precisely calibrated by the manufacturer
and is therefore fully interchangeable without adjustment.
Both the linearity error as well as temperature drift are
corrected “OnChip” through computation resulting in an
outstanding accuracy over a wide range of applications.
The high chemical resistance, dew formation resistant
design and an excellent long-term stability speaks for
itself.
