A NEW member of our Crowtail, believe it can promote your work efficiency. The AC current sensor is based on Current transformers, it transforms the big AC current to little, and then convert 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 house & building.
