Setup

Currently, the following sensors are supported:

• SHTC1
• SHTW2
• SHTC3
• SHT3x
• SHT2x
• SHT85
• STS3x
• SGP30
• SGPC3
• SCD30
• SPS30

At the moment of startup or at any later time by clicking on the ‘Refresh’ button on the top left side, ControlCenter scans all available USB ports for connected SensorBridge devices and  sensors and creates a list of all connected devices on the top left.

Please note that scanning for sensors and devices is only possible while there is no active measurement running.

If you have several SensorBridges with sensors connected, you can identify a specific sensor by clicking on it in your sensor list, which will trigger a pulsation of the LED lights on the SensorBridge port on which the sensor is connected.

To start a measurement, click on ‘Start’ on top left above your list of detected devices and sensors.

This will prompt ControlCenter to start a periodic measurement with the default sampling rate and sensor settings. The data will be displayed at the right side of the UI and will be logged into a file. For each started measurement, a separate log file will be created. In case of an interruption of the measurement for any reason, already recorded data will be still available on disc.

Under ‘File’->’Data Login Settings’, the general ControlCenter settings can be found. Here you can:

• See in which directory the log files are saved and choose a different directory.
• Choose between logging data from each connected sensor into its own log file (default) and logging all data from connected sensors into one single file.

The default file extension is ‘.edf’ and the file format is compatible with Excel. Right-click on the file and choose ‘open with..’ to open it with Excel.

All received data are being plotted on the right side of the UI. They are collected and arranged into Sensor families and signal families. Data of the same kind and of the same unit are displayed together in the same plots. Switch between different plots by using the tab menu on top. Every plot window can be individually undocked. If a re-scan for sensors is performed (click on the ‘Refresh’ button) all the default plots will be reconstructed.

There is the possibility of creating custom plots, which will be displayed in a separate tab. Click on the button ‘Add custom plot’ on the bottom left of the UI. Choose the sensor signals you want in the plot from the list of available signals. Name the plot and click ‘OK’. The custom plot has been created and can be viewed from the tabs menu on top of the plot window.

Optionally, a custom log file can be created for each custom plot, which will contain all sensor signals that have been chosen for the custom plot. To create the custom log file, check the box at the ‘Log’ column next to the plot name in the custom plot list.
Custom plots can be removed by clicking on the remove button in the custom plot list. Removing the custom plot will also turn off logging into the custom log file. This will not remove already recorded log files.

If a re-scan for sensors is performed (click on the ‘Refresh’ button) all the custom plots will be lost. At a later time, the feature to maintain custom plots will be added.

In each plot window, there is a green gear icon on the top right side which opens the plot settings. Here you can:

• Customize the x-axis (time axis) range
• Customize the graph update rate
• Turn autoscaling for the y-axis ‘off/on’ and choose a min. and max. y value if ‘off’, or a min. y-range if ‘on’
• Choose your x-axis format between seconds [s] and clock time [H:M:S]

If a re-scan for sensors is performed (click on the ‘Refresh’ button) the default settings will be restored. At a later time, the feature to remember plot settings will be added.

At startup, ControlCenter checks automatically if a software update for ControlCenter or a firmware update for a connected SensorBridge device is available and offers the possibility to update. Software and Firmware updates are generally recommended since we are continuously working on improving the offered functionality and stability of the platform.

In case you encounter any problems with the ControlCenter software, you can send us the recorded error-log file which can be found here:

C:\Users\<username>\AppData\Local\Sensirion\ControlCenter\Logs\error.log

or accessible under ‘File’ -> ‘Open Error Log Folder’.

Send it to infosensirioncom with a description of your problem and the topic ‘ControlCenter Help’, or use our contact form.

If you have specific wishes for new functionalities or if you have difficulty with any of the ControlCenter features, we would love to know.

Write us a quick note to infosensirioncom with the topic ‘ControlCenter Feedback’, or use our contact form.

Next to each connected sensor in the device list, there is a green gear button in the ‘Config’ column. Here you can set the following functionality, if supported by the connected sensors

• choose a custom name for the sensor which will also be displayed in the plot
• choose the sampling rate within the allowed range
• choose to log less data points in the range of ‘every sample’ to ‘every 10th sample’
• switch the sensor heater ‘on/off’
• turn the alert function ‘on/off’ and customize the alert limits
• restore the alert limits to default settings
• turn ART mode ‘on/off’
• set the measurement mode to ‘normal power / low power’

If a re-scan for sensors is performed (click on the ‘Refresh’ button) the default settings will be restored. At a later time, the feature to remember customized settings will be added.

Next to each connected sensor in the device list, there is a green gear button in the ‘Config’ column. Here you can set the following functionality, if supported by the connected sensors

• choose a custom name for the sensor which will also be displayed in the plot
• choose to log less data points in the range of ‘every sample’ to ‘every 10th sample’
• display and log TVOC/CO₂ Equivalent or Gas Signal (for SGP30)
• display and log TVOC or Gas Signal (for SGPC3)
• choose power mode Low/Ultra low (for SGPC3)
• turn ‘on/off’ humidity compensation and choose a connected SHTxx sensor as source for humidity data
• see information on weather a persistent baseline is set
• if no persistent baseline is set, manually force baseline persistence
• if persistent baseline is set, delete persistent baseline

In case you need to transfer a baseline file for a specific SGP sensor to a different computer, you can find it here: C:\Users\<username>\Local\Sensirion\ControlCenter with the file extension ‘.json’.

If a re-scan for sensors is performed (click on the ‘Refresh’ button) the default settings will be restored. At a later time, the feature to remember customized settings will be added.

Next to each connected sensor in the device list, there is a green gear button in the ‘Config’ column. Here you can set the following functionality, if supported by the connected sensors

• choose to log less data points in the range of ‘every sample’ to ‘every 10th sample’
• turn ‘on/off’ Automatic Self Calibration
• set a reference CO₂ concentration for forced recalibration
• set a temperature offset to compensate for heat sources

If a re-scan for sensors is performed (click on the ‘Refresh’ button) the sensor name and logging options return to default. At a later time, the feature to remember customized settings will be added.
