Abstract

U ovome radu se analizirao i ostvario kapacitivni senzor disanja na PSoC 4 mikrokontroleru. Prikazuju su postojeća rješenja za mjerenje disanja i način rada kapacitivnog senzora. Na kapacitivni senzor se spaja senzorska površina. Razvijene su četiri senzorske površine: žica u obliku kružne petlje, PCB samo sa signalnim vodom, PCB s dodanim uzemljenjem i PCB s dodanom ispunom spojenom na oklop. Za svaku senzorsku površinu se provodi optimizacija parametara u programskom projektu pomoću PSoC Creatora. Senzorom izmjereni signal se s mikrokontrolera pomoću UART a šalje na osobno računalo gdje se u grafičkom sučelju prikazuje valni oblik disanja.

Abstract (english)

In this paper, a capacitive respiration sensor on a PSoC 4 microcontroller was analyzed and realized. Existing solutions for measuring respiration and the mode of operation of the capacitive sensor are shown. A sensor surface is connected to the capacitive sensor. Four sensor surfaces have been developed: a wire in the form of a circular loop, a PCB with signal trace only, a PCB with added ground and a PCB with added shield fill. For each sensor surface, the optimization of parameters in the software project is performed using PSoC Creator. The signal measured by the sensor is sent from the microcontroller using UART to a personal computer where the waveform of respiration is displayed in a graphical interface.
