I2C to USB converter. Sensor cable is connected via plug to this

USB dongle. Either SHT7x or SHT21 on PCB may be plugged to

the cable. Viewer software must be downloaded from the

Sensirion web page.

Product Summary

The evaluation kit EK-H5 is made for running

Sensirion’s humidity and temperature sensors and

display measured values. It is held very simple: A

USB dongle with USB to I

connects with a sensor cable and sensor. With

viewer software it is able to communicate with

SHT1x, SHT7x as well as the new generation SHT2x

and display measured values.

1 EK-H5 USB Stick: Contains USB to I

capabilities.

1 Sensor cable of 1m length with plug for connecting

sensors with USB dongle.

1 SHT21 sensor: SMD type, DFN 3-0 packaged

sensors with version 4C sensor chip mounted to small

PCB with connector. Please refer to datasheet SHT21

for more details.

Version 1.0 – January 2010

The viewer software can be downloaded from the

Sensirion web page and owns some simple data-

logger features.

The main purpose of the evaluation kit is

demonstrating the unique performance of Sensirion’s

humidity and temperature sensors without any own

hard or software design work.

Viewer Software

The viewer software displays relative humidity and

temperature data on two different windows. It allows for

addressing all available resolutions, absolute or relative

timing, free choice of measurement intervals (1 … 1440s),

and choice for displaying °C or °F. The data may be

logged, stored and exported to Excel format.

Viewer Software must be downloaded from the Sensirion

web page. Please find it on www.sensirion.com/ekh5.

Please note that the USB stick, sensor cable and sensor

must be connected to the computer before starting the

software. No further software driver or any other hardware

is required for running EK-H5.

When starting the viewer software, the right sensor must

be selected in a first window (more sensors are given for

choice). The settings must be chosen and then the

measurement may be started.
