functions, this sensor is ideal for this project design [6]. Figure 3: Functional Diagram of MAX30100 Figure 4: MAX30100 with Breakout boardTo start reading from the MAX30100, the chip needs to first be set to a mode of operation, forexample SpO2 + HR mode, which can be done through the registers [19]. This allows the sensorto detect heartbeats as well as start reading IR and Red-light data through the photodetector. TheDC signal needs to be removed from the raw IR data to read the hearth rate and oxygensaturation properly, leaving the AC part only. Only the light absorbance levels from the bloodare needed, which means other absorbance from surrounding tissues and anything else in thefinger and
