anemometer sensorVoltage calculation #14

Closed thijstriemstra closed 4 years ago

thijstriemstra commented 4 years ago

What are these values in code/ESP32/SkyeTracker/src/Anemometer.cpp

double sensorVoltage = -0.000000000000016 * pow(reading, 4) + 0.000000000118171 * pow(reading, 3) - 0.000000301211691 * pow(reading, 2) + 0.001109019271794 * reading + 0.034143524634089;

can you add some code comments for this? do these constants change when using a different anemometer?
