Hello,
I'm developing a logger to measure (store) the current of an electrical equipment using SCT013 of 100A/1V with ADS1115. As the CT has built-in resistor so No burden resistor is being used as described by: https://www.poweruc.pl/blogs/news/non-invasive-sensor-yhdc-sct013-000-ct-used-with-arduino-sct-013
I'm using code given below. The GAIN, I'm using is GAIN_TWO. I can't understand where is going wrong as the output shows 9.25A while actual current is 1.6A (measured by clamp-meter).
Need assistance and if you have already done similar project please share details so I can compare the logics and results.
Code is attached in txt file.
