SCT-010 family is current sensors NON-Invasive which let you measure the current through any conductor without any modification on the installations. It is not necessary to cut or modify the wire. These sensors are ready to be used with Arduino-based PLC or any single Arduino board to measure the intensity or power consumption in a charge.

SCT-010 meters are current transformers, instrumentation devices that provide a proportional measurement across the AC electrical circuit. That measurement is made by electromagnetic induction. This family of sensors includes a split ferromagnetic core (like a clamp) that allows you to open it for winding a conductor on an electrical installation without cutting or modifying the installation.
