The current sensor on my Spider returns zero most of the time. I wrapped it around AC and DC wires, but can’t get a reading. Once in a while I would get a few amps but the values are are all over the ballpark.
I used a timer to get the value every 200 miliseconds.
double current = currentSensor.GetCurrentReading();
string s = "current:" + current.ToString();
Debug.Print(s);
It will only work on AC and it will only work if you hook it around a single wire - I.e. Either Live or Neutral but not both. (Both would cause the magnetic field to cancel out.)
Just connected the current sensor to one of the wires of my lamp and got the current values below. It is not very useful since the values are all over. It didn’t matter wether I hooked it to line or neutral.
