SCT-013-100 non-invasive AC current clamp sensor.

The SCT-013-100 Non-Invasive AC Current Clamp Sensor is a split-core current transformer designed to measure AC current up to 100A without direct electrical contact. Its clamp-on design allows safe and easy installation by simply clipping it around a live wire—no circuit cutting required.

This sensor outputs a proportional analog signal suitable for interfacing with microcontrollers such as Arduino, ESP32, STM32, and Raspberry Pi (using appropriate burden resistor and signal conditioning). It is widely used in energy monitoring systems, smart meters, home automation, solar power monitoring, and industrial current measurement.

With excellent electrical isolation, high accuracy, and robust construction, the SCT-013-100 is ideal for real-time AC current sensing in both educational and professional applications.
