Calculating SPO2 and Heartrate

[IamMugiChan]

Hi there

I have successfully run the sample file however is it possible to compute

Heart Rate and SpO2 using this library?

Hi,

this library has the only scope of providing you an access to the MAX30102 sensor when using MicroPython. Therefore, you can only get the RAW data.

To compute HR and SpO2, you have to code your own application. I left some hints about that here. There are some C++ implementations that could be ported in Python.

Feel free to start a new discussion if you want to ask the community or to share your findings (greatly appreciated). Also, you may take a look or start a new thread on MicroPyhton forum.

Bye, Nicola

Device Used: mh-et live max30102 Library Used: https://pypi.org/project/micropython-max30102/

Reading Sample No Finger Input: `

• 130 , 114

• 129 , 117

• 128 , 114 ` Reading Sample With Finger Input

• 16338 , 12171

• 15992 , 12597

• 16093 , 12496

• 15879 , 12468

• 16195 , 12467

Now we can say that the device is reading ...

module configuration: sensor.set_sample_rate(400) sensor.set_fifo_average(8) sensor.set_active_leds_amplitude(MAX30105_PULSE_AMP_MEDIUM)

given this data from function red_reading = sensor.pop_red_from_storage() ir_reading = sensor.pop_ir_from_storage()

how can we compute the SpO2 and the Heart Rate? any ideas or sample?
