A spreadsheet and python script that take all the work off your shoulders when calibrating moisture sensors.
The spreadsheet helps you calibrate your moisture sensors for accurate readings in coco coir or any other substrate. It is filled with helpful formulas that make the entire calibration process straightforward and easy to track.
The python script calculates the coefficients a2, a1 and a0 based on the data entered in the spreadsheet, which can then be enterd in the equation that calculates the VWC.
python script:
Customizable Polynomial Fitting: Choose the degree of polynomial that best fits your sensor's response curve
Easy Data Input: Uses environment variables to store calibration data points
Comprehensive Analysis: Calculates and displays important metrics (MSE, RMSE, SEM) to evaluate calibration quality
Visual Validation: Generates three informative plots:
