Datasheet Evaluation Kit EK-H5
For Humidity and Temperature Sensors
 Simple and easy-to-use evaluation kit
 Viewer software available for download
 USB Interface
Product Summary
The evaluation kit is made for running Sensirion’s humidity
and temperature sensors. It is held very compact: a USB
dongle with USB to I
2
C translator capabilities allows
connecting the sensor directly to the USB port. With the
accompanying viewer software it is possible to
communicate with the sensors, display measured values
and export data into a csv file. The evaluation kit is
available in two versions. The standard version is available
for sensors that can operate at 3.3 V, while the 1.8V
version is for the sensors operated at 1.8 V.
The viewer software can be downloaded from the
Sensirion web page and allows logging data and changing
resolution for SHT2x, SHTC1, SHT7x/SHT1x and for
STSC1, STS21. For the SHT3x sensor series it is possible
to use the alert function, the internal heater as well as the
ART function. The main purpose of the evaluation kit is to
demonstrate the unique performance of Sensirion’s
humidity and temperature sensor without the requirement
of any hardware or software design work.

Set-Up of EK-H5 1.8V (Order No. 1-101021-02)
Figure 2 Schematic of Evaluation Kit EK-H5 1.8V.
Material Contents
 1 EK-H5 USB Stick: Contains USB to I
2
C translator
capabilities.
 1 Sensor cable of 1m length with a plug for
connecting with USB dongle and a ZIF connector for
connecting with a sensor on FPCB. Please note that a
level shifter board is integrated into the cable. This
level shifter converts the 3.3V on the USB dongle side
to 1.8V on the sensor side.
 1 SHTC1 sensor: mounted on FPCB.
 1 SHTW1 sensor: mounted on FPCB.
 1 STSC1 sensor: mounted on FPCB.
Please note that 1.8V sensors must be operated with the
cable supplied in the EK-H5 1.8V which contains the level
shifter that converts the voltage level of 3.3 V on the USB
dongle side to 1.8V on the sensor side. Using the wrong
supply can damage the sensor.
