Data visualization and logging
DracalView
DracalView is a free software from Dracal Technologies for logging data from our USB sensors. It features an easy-to-use graphical user interface that supports all of our sensors communicating via the USB protocol. The built-in graphical module provides a quick and easy way to view data in real time. It also saves data in text files (configurable format) for importing into a spreadsheet or graphics software for later analysis.
- Works under Windows (Win7/8/10 64&32-bit), Mac OS X and Linux
- Supports the simultaneous use of an unlimited number of Dracal sensors on the same computer
- Simultaneous and synchronized recording of all types of sensors
- Records captured data to text files (configurable format)
- The recording file can be viewed in real time (new values are added dynamically)
- Easy-to-use calibration manager for our calibratable products
- Up to 50 additionnal channels allowing the use of mathematical formulas
The DracalView download comes with our free command line tool dracal-usb-get.
This tool, which DracalView shares the resources, allows you to directly access your data and gives you all the autonomy you need to integrate them into other programs.
- Works under Windows (Win7/8/10 64&32-bit), Mac OS X and Linux (instructions) available
- Simultaneous and synchronized recording of all types of sensors
- Sensor interrogation by unique serial number
- Export to stdout
- Configurable measurement units (°C, °F, Kelvin…)
- Code examples in numerous programming languages available
- One concrete example of integration within LabVIEW available
Command-line interface for wireless data integration
dracal-sensgate-get
The DracalView download also includes dracal-sensgate-get, a command-line-interface that provides wireless access to data from all the sensors connected to your SensGate. The tool is designed so that code already written with dracal-usb-get can also be used with dracal-sensgate-get, up to a simple “search and replace”.
This tool offers the same advantages as those for dracal-usb-get listed above, plus:
- Access data from any Sensgate-connected sensor, even those communicating via COM protocol (VCP option)
