Is there a published Calibration curve/lookup table for this sensor to compute SPO2?
There are calibration tables and additional information for those tables, but nothing regarding the MAX30101 EV kit. I've searched a lot of websites for this information, and it appears that nothing really exists which means it either doesn't support it or it hasn't been developed yet.
However, developers have a page with details you can use to contact them. Use the following link to reach that page: https://www.maximintegrated.com/en/aboutus/contact-us.html
