Current AC Single-phase Transformer Module

Measuring AC current with an Arduino can be a little tricky, but with the TA12-100 current transformer module, it becomes much more manageable. This module features a precision micro current transformer and is ideal for sensing AC current up to 5A. It outputs a small analog signal (5mA) proportional to the current, which can be easily read by an Arduino or similar microcontroller. Ideal for energy monitoring and DIY current-sensing applications.
