Product Summary
The evaluation kit EK-H4 is made for running
Sensirion’s humidity and temperature sensors and
display measured values. It is able to communicate
with SHT1x, SHT7x as well as the new generation
SHT2x and display the measurement values on a
display on the multiplexer. The main purpose of the
evaluation
performance of Sensirion’s humidity and temperature
sensors without any own hard or software design

Version 1.1 – May 2010
In connection with a computer and specific software
supplied with the evaluation kit it may also be used
as
measurements. The multiplexer with 4 ports is
connected to the computer via USB interface. The
software may record and display humidity and
temperature values as well as calculated values of
dew point and power consumption. Various
multiplexer boxes with sensors may be run by same
software across various USB interfaces.
Material Contents
EK-H4 contains the following components, enclosed in a
handy suitcase:
