Usage Guidelines and Applications
Operation – DracalView
We recommend launching DracalView to check if the instrument is connected correctly and works as expected. Here are the main steps of the GettingStarted with DracalView guide.
- Connect an instrument.
Launch DracalView. - Verify the instrument appears in the Sources tab.
- Modify units and decimals in the Configuration tab (Optional).
- Customize the names of channels to record in the Sources tab (Optional).
- Visualize data on GraphView.
Please refer to the USB-I2C-SPS30 page for the complete guide, specifically the “Software & Documentation” tab.
Of note, to log data with DracalView, these are the remaining main steps of the Getting Started guide: - Initiate the logging task in the Logging tab.
- Keep an eye on data with BigView.
Watch an introductory video for a quick overview of setting up and logging data in less than 3 minutes.
Operation – Command-line interface
The command-line tools are available with the download of DracalView. In the Getting Started guide, locate them and call the -h (help) argument, whether on a Windows, MacOS X, or Linux-based computer. For complete documentation on how to use dracal-usb-get or dracal-sensgate-get, code examples, and integrating sensor data into LabVIEW™, click on the relevant link in the same Getting Started guide. Briefly, to log data to a file, here is the command linDraculaal-usb-get -s [serial number] -i [chosen channels] -L [location]
To redirect the output, give the argument -L the parameter “- ” to have a stdout output.
Operation – COM Protocol
“VCP-” prefix: If present, the product is equipped with the virtual COM port (VCP) option, which allows it to be freely converted between USB and VCP modes. It is delivered in USB mode.
- To convert the product from USB to VCP mode,
- Open a command-line terminal.
Call “dracal-usb-set -f set_protocol VCP” and disconnect the product. To reverse the product back to USB mode, Send the “PROTOCOL USB” command and disconnect the product.
Please note that under Windows, once an instrument is converted to VCP, it is not recognizable by DracalView and the command-line tools. For additional information, please click the relevant link in the Software & Documentation section of the USB-I2C-SPS30 page.
Calibration
“-CAL” suffix: If present, the product is equipped with a 3-point user-calibration mechanism. The Getting Started guide for calibration is summarized as follows:
- Determine the calibration points.
- Perform the calibration using DracalView or dracal-usb-cal.
A comprehensive video tutorial on the best practices for calibrating instruments using DracalView can be found here.
The Getting Started guide for successful calibration, mentioned in this section, provides many tips and complementary documentation.
Care, Storage, and Recalibration
Care
Use within the specifications in this manual.
NOTE Note that this product is not waterproof and requires protection if contact with water is possible.
Storage
Store within these housing temperature and humidity ranges 0 °C to 70 °C, 10 %RH to 90 %RH.
Recalibration
Dracal’s measuring instruments are factory-calibrated. It is possible to purchase a calibration certificate traceable to the SI along with the instrument and receive a calibrated instrument. This calibration is performed by an ISO17025-accredited laboratory. If the instrument has a “-CAL” suffix, it can be adjusted for accuracy during the calibration. The long-term drift of the USB-I2C-SPS30 is 1.25 µg/m3 per year, for concentrations of 0 to 100 µg/m3. For higher concentrations, it is 1.25 m/v per year.
Troubleshooting Guide and Support
Troubleshooting
TIP Avoid installing the sensor in a location where strong vibration is likely to occur. Strong vibrations may cause slight inaccuracies in the reading. Feel free to browse the website’s Resources section for any supplementary information. Here are interesting articles

Both a Wi-Fi/Ethernet gateway for Dracal’s sensors and a data logger, fulfill the needs of customers requiring a remote solution to precision data acquisition.
Disassembly and Environmental Considerations
Disassembly Instructions
- Turn Off Power Before disassembling the USB sensor, ensure it is disconnected from any USB port.
- Remove External Connections Unplug any cables connected to the USB sensor.
- Identify Screws and Fasteners Locate and identify any screws or fasteners securing the casing of the USB sensor.
- Separate Casing Gently separate the casing; be careful about damaging internal components. If resistance is encountered, recheck for any overlooked screws.
- Document Component Positions Before further disassembly, document the positions of internal components for ease of reassembly. Handle Components with Care: Handle internal components carefully to avoid electrostatic discharge and damage. Use an ESD (Electrostatic Discharge) mat or wrist strap if available.
- Follow Reverse Order for Reassembly When reassembling the USB sensor, follow the disassembly steps in reverse order, ensuring components are correctly positioned and secured. Environmental Considerations
- Recycling Recommendations Dispose of components and packaging materials by local recycling regulations. Check with local authorities for proper e-waste disposal facilities. Reuse Opportunities: Consider reusing components or donating functional parts to minimize environmental impact.
- Minimize Energy Consumption Power down or disconnect the USB sensor when not in use to minimize energy consumption.
