The SCT-013 uses electromagnetic induction — as current flows through the wire, a proportional signal is produced at the output jack, which can then be read by a microcontroller or energy monitor without any need to cut or interrupt the circuit.\u003c\/p\u003e\n\u003ch4\u003eQ: Which model should I choose — 30A, 50A, or 100A?\u003c\/h4\u003e\n\u003cp\u003eA: Choose based on the maximum AC current you expect to measure. The SCT-013-030 is suited for circuits up to 30A, the SCT-013-050 for up to 50A, and the SCT-013-000 for up to 100A. For typical household circuits or small appliances, the 30A or 50A models are usually sufficient. For larger loads such as main supply lines, the 100A model is recommended.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this sensor compatible with Arduino and Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The SCT-013 series is widely used with Arduino, Raspberry Pi, and other microcontroller platforms for DIY energy monitoring. It outputs a signal via a standard 3.5mm jack, which can be connected to an analog input (typically with a burden resistor and voltage divider) to read AC current values in your code.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use this sensor outdoors?\u003c\/h4\u003e\n\u003cp\u003eA: The SCT-013 operates across a temperature range of -25°C to +70°C, making it suitable for a variety of environments. However, it is not rated as weatherproof or waterproof, so adequate enclosure protection is recommended for outdoor installations.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is a split core current transformer and how does the SCT-013 work?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"A split core current transformer is a non-invasive sensor that measures AC current by clamping around a single conductor.
