Figure 1 Schematic of the Evaluation Kit EK-H4. The Evaluation
Kit works without connection to a computer it only needs a
connection to the power socket. Optionally, the EK-H4 can be
connected to a computer and operated through the Viewer
Software.
Device Certification
The Evaluation Kit EK-H4 is RoHS and WEEE compliant.

Product Summary
The evaluation kit EK-H4 is made for running
Sensirion’s humidity and temperature sensors and to
display measured values. It is able to communicate
with SHT1x, SHT7x, SHT2x, SHT3x, SHTC1 and
SHTW1. The measured values will be displayed on
the display of the EK-H4. The main purpose of the
evaluation kit is to demonstrate the unique
performance of Sensirion’s humidity and temperature
sensors without any own hard or software design
work. Together with a computer and a dedicated
Viewer software (see
sensirion.com/ek-h4
) it may also
be used as a data-logger for simple experimental
measurements. The EK-H4 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
absolute humidity. It is possible to connect multiple
EK-H4 to different USB ports on the same computer
and operate them through the same Viewer
Software.
