I’m working on a science fair project that uses the as7265x triad spectral sensor to measure macronutrients in water for hydroponic solutions. I’ve managed to setup the sensor with an esp32 microcontroller, and I’ve looked at a number of research papers which have tried something similar, however, no clear instructions are given on calibration. Please help clarify.
