ZMPT101B single-phase AC voltage sensor transformer module for measuring AC voltage in electronics and microcontroller projects. This module can measure AC voltages up to ±250V at 50Hz/60Hz and outputs a scaled-down AC voltage signal between 0V and VCC with a DC offset of VCC/2.

Suitable for AC voltage monitoring, energy meter projects, power measurement circuits, mains detection projects and Arduino-style AC sensing applications. Use proper electrical safety precautions when working with mains voltage.
