SENSIRION SENEVAL-SCB4XV1 Evaluation Board
Technical Description SENSEVAL-SCB4XV1
Evaluation board for Humidity, Temperature, Volatile Organic Compounds and
Pressure
- Evaluation board with SHT40 (Humidity/Temperature), SGP40 (Volatile Organic Compounds) and LPS22DF (Barometric Pressure)
- Compatible with the STMicroelectronics DIL 24 socket
- Supported by the STEVAL-MKI109V3 Motherboard
- Compatible with STM32Nucleo and STM32Cube Software
- 1.7 V to 3.6 V supply voltage range
Product Summary
The evaluation kit for the Sensirion SHT40 (relative humidity and
temperature), Sensirion’s SGP40 (Volatile Organic Compounds) and
STMicroelectronics LPS22DF (Barometric pressure) enables easy sensor
evaluation and facilitated prototyping. This Evaluation Board is compatible
with the STMicroelectronics DIL 24 socket and is supported by the STEVAL-
MKI109V3 motherboard. The Evaluation Board is also compatible with the
STM32Nucleo boards from STMicroelectronics.This technical description is
limited to the SENSEVAL-SCB4XV1 evaluation board. For more information on the
individual sensor specifications, please consult the datasheets linked from
the product page. The combination of sensors on this evaluation board allows
to evaluate ideas requiring relative humidity, temperature, volatile organic
compounds and barometric pressure. It can serve both as a platform for
evaluating the individual sensors and to prototype ideas using one or multiple
of these sensors.

Evaluation using the Professional MEMS Motherboard MKI109V3
The SENSEVAL-SCB4XV1 is compatible with the ST MEMS Motherboard MKI109V3 through the DIL24 connector. SENSEVAL needs to be connected so that the Sensirion and ST logos on the evaluation board are in the same direction as the ST logo on the MKI109V3. The STEVAL-MKI109V3 firmware needs to be compatible with Unico GUI version 9.14 and above. To update the firmware on STEVAL-MKI109V3:
- Download and install the latest Unico GUI from the ST Website
- Locate the downloaded file, navigate to the FIRMWARE folder and then to the ProfiMEMSTool board and locate the .bin file. You will need this for the firmware update
- Download and install the STM32CubeProgrammer software
- Make the MKI109V3 boot in DFU mode by following the instructions in chapter 2.2 of the MKI109V3 user manual
- Upgrade the firmware using the .bin file from step 2 and the instructions in chapter 2.2.2 2 of the MKI109V3 user manual
As soon as the MKI109V3 is updated with the latest firmware you can launch the
Unico GUI. Select the SENSEVAL-SCB4XV1 (SHT4x + SGP40 + LPS22DF) from the
environmental sensors tab and click on Select Device. The GUI should look like
the figure below:
To start measuring navigate to the Options tab and click on Easy Configuration
(1) and then on Start (2) at the top of Unico GUI. 
Figure 3: Unico GUI, Options tab
You can see the measurements by clicking the two plot buttons on the right of the application (3):
Figure 4: Unico GUI Plot windows
Unico GUI, allows the measurements to be saved in a file, to save the data:

- Browse the folder and name the log file according to your liking,
- Select the data you would like saved,
- Start logging
- Start the measurement of the sensor
Evaluation using a Nucleo Board and a Nucleo Expansion Board
Hardware Setup
“STMicroelectronics with the latest release of X-CUBE-MEMS-1 functional
package (Version 10.0.0) support the three sensors provided on the SENSEVAL
board.” Users can quickly evaluate the performance of the sensor via the use
of Unicleo-GUI provided by STMicroelectronics (Version 1.23.0). The support is
currently limited to the NUCLEO-F401RE board and the X-NUCLEO-IKS01A3
expansion board.
To get started with the evaluation make sure you have the correct hardware as
mentioned above and connect the expansion board on the X-NUCLEO-F401RE.
Afterwards, connect the SENSEVAL-SCB4XV1 on the expansion board using the
DIL24 socket. Make sure that the Sensirion and ST logo on the SENSEVAL-SCB4XV1
is facing the same direction as the ST logo on the X-NUCLEO-IKS01A3 expansion
board. The setup should look like the picture below:
Figure 5: the evaluation board mounted on the X-NUCLEO-IKS01A3 expansion board with the Nucleo F401RE board (Note: this picture is showing the predecessor of the SENSEVAL-SCB4XV1, the SENSEVAL-SHT4XV1)
Firmware update
The firmware on the Nucleo F401RE board needs to be flashed so that it can
work with UNICLEO GUI. STMicrolectronics provides an example to get things
started with the X-CUBE-MEMS-1 functional package. To update the firmware you
can use STM32cubeProgrammer and load the ready-made example by navigating to
the folder of the X-CUBE-MEMS-1 functional package: “en.x-cube-mems1\Projects
