Informatie (ENG) The SCT013 series are sensors of non-invasive, current transformers that measure the intensity of a current that crosses a conductor without needing to cut or modify the conductor itself. We can use these sensors with a processor, like Arduino, to measure the intensity or power consumed by a …
Leakage current of your Arduino input pin likely limits the accuracy, especially for low-light measurements. Leakage current of the photodiode is probably less than that of Arduino, but also impacts low-light accuracy. Leakage currents are affected greatly by temperature. If …
