Skin and Body Temperature Parameter Calibration of MAX30100 Sensor Module Based on Arduino-Uno

Abstract

The aim of this research is to process the temperature parameter's Arduino digital output and convert it into skin and body temperature through calibration effort. Firstly, we compare the characteristic of temperature change's aspect with DS18B20 temperature sensor in skin temperature reading. The calibration effort’s process has four leading stages sequencingly: averaging, filtering, fitting (nearing) towards skin temperature's reading, and lastly nearing the result to body thermometer as calibrator. The fitting result respectively has ammount of 6.02°C for skin temperature and 1.34°C for body temperature. According to these following results, the error rate is ±0.27% towards body thermometer.
