CT clamp burden resistor calibration for ADS1115 on Raspberry Pi: pick the external burden, stabilise with a decoupling cap, and apply the DC-bias correction that separates a stable watt reading from drift — with the 51 Ω + 10 µF combination I actually measured.
ADS1115 and CT clamps for whole-house energy monitoring on a Raspberry Pi: 15.6 days of real 60-second watt data, RMS burst code, and the calibration constant hiding a scale error.
