The SCT-013 100A non-invasive AC current sensor is a clamp-style current transformer used to measure the electrical current flowing through a wire without cutting or disconnecting it. You simply clip the sensor around a single AC conductor and it outputs a small signal that a microcontroller or monitoring board can read. It is a popular choice for makers, electricians, and anyone building an energy-monitoring or automation setup at home, on the farm, or in a workshop.
Key features
- Non-invasive clamp design — clips around the wire, no need to cut the cable.
- SCT-013 model rated for AC current measurement up to 100A.
- Compatible with common microcontroller and energy-monitor projects (Arduino, ESP, and similar boards).
- Easy to install and reuse across different circuits and projects.
Typical uses
- Monitoring the power draw of pumps, motors, and irrigation equipment.
- DIY home and farm energy-monitoring dashboards.
- Automation, IoT, and smart-power logging projects.
How to choose / tips
- Confirm the current you want to measure stays within the sensor's rated range.
- Clamp around one conductor only (not the full cable) for an accurate reading.
- Check whether your project needs a burden resistor or voltage-output version for your board.
