Calibrated humidity module
HYTE-ANA-1735
Description
Description
Features
Off late, humidity measurement has found entry into many mass produ-
ced items like ventilation and household appliances or automotive ap-
plications. Normally for such products, a fully integrated and calibrated
sub-module is required which can result into an attractive system price
with a standard calibrated interface.
The B+B humidity module combines the most modern thin film sensor
technology with flexible, digital signal processing of an ASIC and pre
-
sents an optimum price performance ratio.
The high quality, capacitive humidity sensor guarantees highest measu-
ring accuracy, drift stability, weather resistance as well as an outstanding
long-term stability. Moreover, after long saturation phase, the measured
value builds up very fast.
The calibrated humidity and temperature values are transmitted over the
analogue output with high accuracy and resolution, which enables simp-
le integration into customised products. The calibrated output signal gu-
arantees simple integration of the sub-system during development pha-
se, which results in the shortest time-to-market product developments.
Additionally, temperature can also be determined over the brought out
NTC, which enables calculation of dew point or absolute humidity.
