HEROxS : Heart Rate and Oxygen Saturation Meter.

Abstract

Heart rate (HR) and oxygen saturation (SpO2) are two key indicators for evaluating the cardiovascular condition of a person and detecting potential health issues. Hence, there is a need for portable solutions that can provide daily and accurate monitoring of these signals, which later can be evaluated by a healthcare professional. This work presents the design of a device capable of HR and SpO2 monitoring, consisting of a 0.91-inch OLED display that shows real-time measured values, a MSP430G2553 microcontroller and a SEN-15219 sensor board. Experimental results show that the accuracy is very good (less than 2 % of absolute error) and the autonomy can be up to 15 days.
