I am trying to find out what is the linear equation that the ACS712 20A Current Sensor uses. I have attached the code below. /* Measuring Current Using ACS712 */ const int analogIn = A1; int mVperAmp = 100; // use 100 for 20A Module and 66 for 30A Module int RawValue= 0; int ACSoffset = 2500; doub…
