I am working on a small home project 'glucose meter' via non invasive techniques. I am using four sensors like RGB color sensor, two multi-wavelength photo diodes (A & B) and temperature sensor (K-Type Thermocouple). I am using Multi Regression algorithm to estimate Glucose level in human body by calculate all four readings from sensors.
I am using ESP32 and I am saving all my sensors data in a CSV file (or text) after taking more than 20 calibration data from my family and friends. I can read this file after writing but I am facing a problem in reading all calibration data from this text/CSV file in the following particular manner.
Y,Sensor1,Sensor2,Sensor3,Sensor4 92,103,25,65,9875 91,104,26,62,9805 105,92,30,66,9600 150,60,40,75,9233 ...,...,...,.....
Above pattern indicates 'Y' values (Blood Sugar value mg/dl) and corresponding sensors value on that time. I am facing problem in reading these object like:
Y1 = 92, S1 = 103, S2 = 25, S3 = 65, S4 = 9875 Y2 = 91, S1 = 104, S2 = 26, S3 = 62, S4 = 9805 ....................AND so forth.............. Y1000 = XX, S1 = XX, S2 = XX, S3 = XX, S4 = XX
Can any one help me how would I read and categorize each sensor values from the text/CSV File?
