Efficient engineering: Follow the assembly progress of your system live. The perfect addition to the SO3 engineering platform: with the SO3 app, the assembly progress of a system can be tracked in real time with a smartphone or tablet. When assembling a system, the fitters scan special QR codes on site in each section, which means that the assembly progress is transmitted directly to the SO3 database. This allows you to determine at any time whether the project is on schedule and when it is likely to be completed. Please note: The SO3 app can only be used in connection with the SO3 engineering platform. SO3 - the future-oriented engineering platform from SCIO Automation. As a powerful online planning tool, SO3 brings together all those involved in an engineering process and thus enables a design process that can be designed consistently transparent and safe from the first concept to commissioning. Since planners, clients and operators can work together directly regardless of their geographical location, project efficiency increases over the long term.

A logger App that can measure acceleration, gyroscope, and magnetic field synchronously, then export as a CSV file. The measured values can be visualized in real-time by enabling "Realtime visualization". On the other hand, when you want to measure at a more accurate frequency, disabling "Realtime visualization" is preferred. Also, if the sampling rate is set too high, the same value may be sampled many times depending on the hardware specifications.
