hi i have problem that i am using ACS712 20A current Sensor ZMPT101B voltage sensor directly connected to arduino
i changed the calibration as follow
emon1.voltage(A1, 580, 1.7); // Voltage: input pin, calibration, phase_shift
emon1.current(A0, 9.5); // Current: input pin, calibration.
v rms and I rms is right but real power and pf is not correct ( not equal to my wattmeter reading ) !!!
if any one can help >. please mail me
