HLW8012 board calibration
seams this one is also becoming popular.
but i'm not find out to calibarte it. any help?
Thx in advance.
You have a calibration example in the "HLW8012_Interrupts" example. It returns the multipliers you can use on library setup with the setCurrentMultiplier, setVoltageMultiplier and setPowerMultiplier.
i used the HLW8012_Basic example, with no luck.
By calibrate section, i setted:
400W (my toaster) 127V (my AC mains, according my MM and 400/127
// Calibrate using a 60W bulb (pure resistive) on a 230V line hlw8012.expectedActivePower(60.0); hlw8012.expectedVoltage(230.0); hlw8012.expectedCurrent(60.0 / 230.0);
got the multipliers, used it, bit output does not shows 127, 400, etc....
