Making it easier for Arduino, PLC, and data loggers to acquire current signals—the transmitter version of SCT013

TST013: The Easiest Way to Use Split‑Core Current Transformers with Arduino, PLCs & Data Loggers

If you work with Arduino, PLCs, industrial controllers, or data loggers, you already know the SCT013 split‑core current transformer.
It’s popular, safe, and easy to install — but not always easy to use. Traditional SCT013 sensors output a small AC signal, which requires
rectification, biasing, filtering, and calibration before any controller can read it.

Even the Gravity SCT013 module sold on Botland converts the AC signal into a 0–1V DC analog output to make it compatible with Arduino systems.
This proves one thing clearly: users want SCT013 to be plug‑and‑play.

That’s exactly why we created the TST013 Series.

Meet TST013 — The SCT013 You Can Use Instantly

The TST013 split‑core current transmitter is the upgraded, professional version of SCT013. It keeps the same safe, clamp‑on design —
but adds a fully integrated signal‑conditioning module inside.
