Has anyone tried to use this particular sensor (SCT-013-000) with that particular Arduino (MKR 1300)? Cause I keep getting different results when connecting Arduino UNO and then trying the MKR, both connected to the 5 V. As for the resistors I have been using both 10 kΩ resistors and the 33 Ω for burden, calibration at 60.6 and sampling at 1480. Basically, everything configurated with the help of the guide on this website.
But this isn’t the only issue with this particular set (MKR 1300 + sensor), I tested with an amperometric clamp a 6 A heater and the sensor values were also quite different (8 A on the sensor instead of around 6 A), only when I got the calibration to 38.8 it got close values, but I don’t think it works for every current, but since the calibration should be a fixed value based on the burden resistor and the sensor it doesn’t make much sense for me.
