Abstract

U radu je opisan bežični senzorski čvor MUHA, temeljen na nRF51422 sustavu na čipu, zajedno s glavnim funkcionalnostima. Dizajnirana je i implementirana programska potpora u C programskom jeziku. Istražene su i evaluirane dvije metode primanja podataka na računalu putem Bluetooth Low Energy (BLE) tehnologije. Nakon toga je napravljena validacija EKG i inercijskog senzora slanjem preko BLE tehnologije čime je potvrđena glavna funkcionalnost. Prikazani su rezultati primljenih signala na računalu s mjerenjima tijekom kojih su korištene različite frekvencije uzorkovanja signala na senzorima.

Abstract (english)

Master's thesis describes wireless sensor node MUHA, based on nRF51422 system on chip, along with its main functionalities. Software support for the node is designed and implemented in C programming language. Two different methods of receiving data using Bluetooth Low Energy (BLE) on computer are explored and evaluated. Following that, evaluation of both ECG and inertial sensor, along with full system is presented by sending data through BLE, which confirmed main functionalities. In the end, results of computer received signal data with variable sampling frequencies of sensors is shown.
