SCT-013 30A AC Current Sensor Split Core Open-Close Current Transformer 30A Non-Invasive

The AC current sensor is based on Current transformers, it transforms the big AC current to little, and then converts to voltage with the build-in resistor so users can get the AC current value via measuring the output voltage with any microcontroller such as Arduino. The split-core type makes this sensor suitable for DIY usage such as energy monitoring for houses & buildings.
