The SCT-013-000 30A/1V Switching Current Transformer is a non-invasive AC current sensor designed for safe and accurate measurement of electrical current without the need to cut or modify existing wiring. Using a clamp-on split-core design, it easily clips around a live conductor to detect current flow and convert it into a proportional voltage signal that can be read by microcontrollers such as Arduino, ESP32, or other monitoring systems.
This sensor is widely used in energy monitoring, power measurement, smart home systems, and IoT energy projects. Its compact design and insulated casing make it safe, reliable, and easy to install in both prototyping and permanent monitoring setups.
