Usage of inercial sensors is widespread in many areas, especially in aueronautics. Another field of use for such sensors is capturing and recognizing gestures from sensors placed on human body parts, for example hand or shoulder. This article is dealing with a proposal of weareable sensors, capable of detecting simple gestures such as rotation, elevation, movement etc.. System will be based on STM32 platform, which will guarantee low energy consumption and sufficient performance to evaluate the captured motions. Multilayer neural network capable of recognizing the elementary gestures was designed to detect movements such as hand rotations, hand vertical and horizontal movements
