I’m using a CT013 - 100A connected to a 51ohm burden resistor. Also I have follow the guide, so I have One capacitor of 10µF and 2 equal resistor of 10K ohm. I use a D1 mini connected to a ADS1115.
For burden, I calculated base also on the guide provided with a current RMS of 40A and 3,3v as input of ADS1115.
Schema: I don’t have a good picture to share but you can refer to the guide or Energy Tracking with ESP32 + CT Clamp Sensor from an Efergy elite 1.0R
The gain is on ADS and not on ct_clamp. I already modified to something more logic 2.048V
