Sensing as a Service Model for Pulse Oximeter Supported by Internet of Things

Abstract: The purpose of this paper is an approach to recognize oxygen level in people�s blood. Our method uses SPO2 sensor (Blood oxygen saturation level) and msp432. By using SPO2 sensor to sense oxygen level in the blood and Beer�s Lambert Laws to get oxygen level value and that oxygen level value display in LCD. The proposed method require less no of hardware so it reduced the production cost.

Keywords: SPO2, MSP432, Power supply, LCD module, Readings.
