SensorConnect
Free
SensorConnect is the next generation in desktop sensing software.
From configuration of nodes and starting networks, to collecting and analyzing data in real-time, SensorConnect provides a modern, powerful experience with our Wireless, Inertial, and Displacement products.
Using our intelligent data collection and graphing algorithms, you are able to visualize massive amounts of data instantly, and then zoom in on points of interest just as fast.
Built in MathEngine functionality allows for both real-time and post-processed math, such as generating FFTs, averages, RMS, etc.
{MSCL}
Free and open source API
The MicroStrain Communication Library (MSCL) makes it simple to write code that interacts with our Wireless, Inertial, and Displacement sensors.
MSCL is completely open source and hosted on GitHub under the MIT license.
Full documentation, example code, and a quick start guide are provided to help you get started.
Available for C++, Python, and .NET.
ROS
Robot Operating System (ROS) is an open-source, meta-operating system for your robot. It provides the services you would expect from an operating system, including hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management. ROS can be used in building and simulating robotics applications, as well as unmanned ground vehicles and simultaneous localization and mapping (SLAM). To facilitate better integration within the ROS ecosystem Microstrain has develop an open source License free (MIT License) series of drivers specifically designed and tested for ROS.
