Which processor do you use to control the i²c bus? Which programming environment (assembler, C, Python, ...)?
Have you tried to locate a library for your processor/programming environment and the MAX30102?
Have you tried to locate a library for your processor/programming environment and the MAX30102?
I'm using nodemcu and will be coding with Arduino IDE. Yes, i do have the libraries needed for it. I just don't know how to code it. Along with this sensor, i have the max30205 as well. Once i get the unique address of the device, i can use wire.requestfrom() to communicate with it right?
So i do have the code for reading data from each individual sensor cuz i have the libraries for it. So do i just hit requestfrom() and initiate communication with that device, use the code from that particular library and then request from the other sensor and do the same?

The source page for the library has example code.
Yes I've seen it but my question is, once i use wire.requestfrom() to request data, is the data only retrievable with wire.read() or can the functions from these libraries be used to do retrieve them?
wire.read gets the data from an i2c device.
Which other functions would you want to use?

If the libraries are designed for i2c: yes.
If not: no.
What a library can do or not you'll have to find in the README for the library or by studying the code of the library and the examples. You'll find useful hints in the comments of the examples (usually).
It is common for such libraries to offer different layers of abstraction. You may find sensor_read() functions that deliver raw sensor data, but also higher level functions like gettemp() that convert the raw data into a user friendly format.
What exactly -> see the library's documentation.
