I am working with ESP32 and AHT25 sensor to get temperature and humidity values. I want to store that temperature and humidity values in EEPROM. I don't know much about storing data's in EEPROM. Can anyone please tell me how to do this?

And also I need to fetch that data from EEPROM and update into EXCEL file. I am creating GUI using Tkinter. My need is if I create a button in my GUI like DOWNLOAD EXCEL, when I click this button the temperature, humidity data's from excel file (EEPROM Data updated in EXCEL File) should be download. I think it's a big process. Still I have no idea about how to do this. Can anyone guide me?

Since I do not have enough reputation for clarifying comments, I will try to present the task. There are two temperature and humidity sensors, there is an EEPROM device. I can only assume that this is an arduino. We need the sensor data to get into excel.

EEPROM has 10,000 to 100,000 rewrite cycles. It will just block after a while. Therefore, we will not write anything into it.

I would send data directly to the computer via the COM port. step by step:

  1. take the documentation for the sensors and look at which register they write the values in, or is there a ready-made library for these sensors
  2. we write c++ code that takes data from sensors and send it to Serial (rs232 is another name in windows - com)
  3. write python code that will connect to the com port on windows and listen
  4. we write the incoming data as a csv file
  5. if necessary, we load data from the excel program

When it works, you can add a graphical interface
