To use the sensor in your schematic, follow these steps to import the necessary files: Download the Files : Search for and download the ZMPT101B Proteus Library
: In real life, this module has a potentiometer for calibration. In Proteus, you may need to adjust the component properties (double-click the device) to set the transformation ratio if the library supports it. Arduino code snippet zmpt101b library for proteus

In the world of embedded systems and power electronics, measuring AC voltage is a common but challenging task. Unlike DC voltage, which can be read directly by a microcontroller’s ADC, AC voltage (like the 110V or 230V from a wall outlet) requires isolation, scaling, and offsetting to be safely processed. The —a precision voltage transformer module—has become the industry favorite for this purpose. It outputs a scaled-down, offset AC signal centered around 2.5V, ready for an Arduino or ESP32. Unlike DC voltage, which can be read directly
If nothing appears, you may need to manually add the library path:
