Measuring of torsion or bending moment on rotating shafts is usually done by four strain gauges connected in Wheatstone bridge. When torsion occurs a plain of maximal tensions is rotated for 45° considering the axis of a shaft. Measurement is relatively easy, the problem occurs when data from rotating shaft is transferred. In this thesis a protocol is designed for a wireless data transfer on the basis of Arduino platform. We tested design on a working prototype. We are interested in the limitations of this concept due to data transfer from the point of measuring to the computer, where the further processing is possible.
