The HS4000-EVK Evaluation Kit is used to assess
the HS4001 High-Performance Relative Humidity
and Temperature Sensor. The hardware allows users
to perform data logging experiments, and it can
communicate through a standard USB interface with
the user’s computer using the Demo Software. This
software can be used to view measurements in real-
time, adjust the resolution of the sensor, configure
measurement parameters, and download previously
logged measurements.
The evaluation board can be powered directly from
the USB port of the user’s computer or from a 1632
coin cell battery to enable fully autonomous
(untethered) data logging.

1.2 Kit Hardware Connections
Complete the following procedure to set up the kit as shown in Figure 3:
1. Install the software from the USB flash drive or download from renesas.com as described in Software
Installation and Setup.
2. Connect one of the HS4001 sensor modules facing up, with or without the extension cable attached, into the
sensor module connector
1
.
3. Connect the USB port
2
of the board to the user’s computer using the supplied USB cable, and ensure
that the power switch
3
on the board is in the USB position. The “USB” LED
4
will light.
4. Run the Demo Software package from the Start menu, and click on the “Measure” button
5
. The
“Measuring” indicator
6
will blink whenever data is being captured.

2. Using the EVK
2.1 Measurement Settings
To change the interval and number of measurements to be made, select Measurement Settings from the Tools
menu, enter the desired values, and then click OK, as shown in Figure 5. For the range of valid settings for these
two entry fields, see Valid Settings Ranges.
Figure 5. Measurement Settings
To change the measurement resolution, select Set Resolution from the Tools menu, select the desired
resolution, and then click OK, as shown in Figure 6. The resolution setting is stored on the sensor, and it will be
the default value applied when measurements are started. Measurement settings can be changed only when no
measurements are being taken.

2.2 Exporting Data
The data displayed in the plotter area can be exported in two different formats.
■To export the measured data points in a Microsoft Excel®compatible comma-separated text file, select Save
Data from the File menu. Create a filename for the data, and select the location where the file will be saved.
■To export the plots themselves as a picture file, right-click on the plot area and select Save Image As. Create
a file name, select the location, and select the file type for the image.
2.3 Data Logging Mode (Untethered)
Disconnect the kit from the computer. Ensure that a battery is inserted in the battery holder on the back of the
board with the positive battery terminal facing away from the board, as shown in Figure 7.
Figure 7. Battery Installation
Complete the following to operate the kit in the data logging mode (see Figure 2 and Figure 3).
1. To set the board to the data logging mode, put the power switch
3
in the “Batt” position.
2. To start data logging, hold the “Start/Stop Logging” button
7
for 3 seconds. The “Measuring” indicator
6
will light for 2 seconds and then start blinking on every logged measurement. This can be disabled to extend
the battery life by toggling the “L2 Enable” switch
8
.
3. To stop data logging, press the “Start/Stop Logging” button. The “Measuring” indicator blinks 3 times to
indicate the end of data logging.
4. To download the logged data to the Demo Software, connect the USB port
2
to the computer using the
supplied USB cable, and ensure that the power switch
3
on the board is in the USB position. The “USB”
LED
4
will light.
5. In the software, select Data Logging from the Tools menu and click on the Download Data button
10
as

2.4 Data Logging Settings
To change the data logging measurement interval, select Data Logging from the Tools menu, and then click on
Change Interval. Enter the desired measurement interval, and click OK.
The data logging resolution can be selected in the same method as described in Valid Settings Ranges. Data
logging settings can only be changed when no measurements are being taken.
2.5 Using the Plotter
The plotter
9
displays the measured relative humidity and temperature data simultaneously versus time (see
Figure 3).
■Hold the left-mouse button, and drag it around an area to zoom onto that area.
■Hold the middle mouse or scroll button, and drag to pan across the plot area.
■To undo a zoom or pan operation, right click on the plot area, and select Un-Zoom (Un-Pan).
■The plot area can always be reset to the default view by right clicking on the plot area and selecting Undo All
Zoom/Pan.
■To display the measurement points on the plotted curves, right click on the plot area and select Show Data
Points. While moving the application window, measurements points will not be plotted.
2.6 Valid Settings Ranges
