Proteus Library — Zmpt101b

Simulating AC voltage measurements is a crucial step in developing smart energy meters, overvoltage protection circuits, and IoT power monitors. The ZMPT101B is the go-to single-phase AC voltage transformer module for these applications due to its high precision and isolation.

Complete Guide to Integrating and Simulating the ZMPT101B Voltage Sensor in Proteus

Connect the terminals to the high-voltage inputs (L and N) of the ZMPT101B module.

Connect VCC to 5V, GND to GND, and the OUT pin to an analog pin (e.g., A0) on your microcontroller simulation model.

Search for a trusted "ZMPT101B Proteus Library zip" online. Ensure the downloaded zip folder contains two essential files: ZMPT101BLibrary.IDX ZMPT101BLibrary.LIB Step 2: Locate Your Proteus Library Folder zmpt101b proteus library

A Proteus simulation of the ZMPT101B is useful for functional verification (e.g., checking ADC scaling, firmware logic) but cannot replace real-world calibration using a known AC source and multimeter.

Because Labcenter Electronics does not include this sensor out-of-the-box, third-party developers have created custom library blocks. These blocks use standard .IDX and .LIB files to render the component visual model and its simulation properties. Steps to Find and Download

Wire the components according to this standard simulation configuration:

Locate your Proteus installation directory. The path varies depending on your software version:

Connect the (Pin 0) of the Arduino to the TXD pin of the Virtual Terminal. Arduino Simulation Code Connect VCC to 5V, GND to GND, and

: Search for "ZMPT101B" or "Voltage Sensor" in the component picker. It typically features terminals for AC input and an analog output for microcontrollers like Arduino.
