SCT-013 Non-Invasive AC Current Sensor
Original price was: ₵100.00.₵95.00Current price is: ₵95.00.
The SCT-013 AC Current Sensor is a non-invasive, split-core current transformer (CT) designed to measure AC current without cutting or interrupting the wire. Simply clamp it around a live conductor to safely and accurately detect current flow in household, industrial, or energy-monitoring applications.
Commonly used with Arduino, ESP32, ESP8266, and energy-monitoring platforms like OpenEnergyMonitor, the SCT-013 series provides stable and reliable AC current measurement through its analog output.
