4. Hardware Setup and Software Operation

Once the GUI installation is complete, connect the Si7013 USB dongle to your PC. Your PC should automatically

recognize the USB dongle and use the newly-installed driver. Next, find the icon for the Si7013 GUI, which should

be easily found under recently-installed programs from the start menu, under Programs

 Silicon Laboratories 

Si70xx Evaluation Software or at

C:\Program Files (x86)\Silicon Laboratories\Si70xx

With all the hardware plugged in and once your PC identifies the USB dongle, launch the GUI.

The GUI itself is simple to use. Figure 7 shows a screenshot of the GUI.

Figure 7. GUI Screen

Note: This is the GUI screen when an additional Si7020-EB is used. The appearance will change according to the number of

sensors detected.

The USB dongle contains one Si7013 relative humidity and temperature sensor and can also support one

additional sensor at connector J2. All Si70xx sensor evaluation boards are supported.

Note: The "postage stamp" boards are used on this connector with the 3-foot flat flexible cable. To use the cable, carefully lift

the darker brown piece of the connector and insert the cable with the metal fingers of the cable facing the metal fingers

of the connector then close the connector on the cable (see also figures 1 and 2). If a new postage stamp board is

inserted into a powered dongle, click the “INIT” button on the GUI.
