Two common measurement goals:
Minimal approach for RMS (assume ADC referenced to Vcc, sample N points evenly across one mains cycle):
Example pseudocode (concise):
const float VCC = 5.0;
const int ADC_MAX = 1023;
const float V_REF = VCC/2;
float calibration = 230.0 / measuredRmsAtMains; // set after calibration
float readRMS(int samplesPerCycle)
long sumSq = 0;
for (int i=0;i<samplesPerCycle;i++)
int a = analogRead(A0);
float v = (a*(VCC/ADC_MAX)) - V_REF;
sumSq += v*v;
delayMicroseconds( (1e6 / mainsFreq) / samplesPerCycle );

is a high-precision voltage transformer module designed for measuring AC voltages up to 250V.
Isolation: It provides galvanic isolation between high-voltage AC mains and low-voltage microcontrollers, protecting the latter from electrical surges.
Output: The module typically outputs an analog signal proportional to the RMS voltage.
Adjustment: It includes an onboard multi-turn potentiometer to calibrate the output amplitude and offset (typically VCC/2). 2. How to Install the Library in Proteus
Since Proteus does not include the ZMPT101B by default, you must manually add the component and model files.
To simulate the ZMPT101B AC Voltage Sensor in Proteus, you need to manually add an external library file, as it is not included in the standard Proteus installation by Labcenter Electronics. 1. Download & Installation
You can find the Proteus library files (.LIB and .IDX) on repositories like GitHub (Karan-nevage) or engineering forums.
Step 1: Download the ZMPT101B library zip file and extract it. Step 2: Copy the .LIB and .IDX files.
Step 3: Navigate to your Proteus installation folder (usually C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY) and paste the files there
Step 4: Restart Proteus. You can now find the sensor by searching " Go to product viewer dialog for this item. " in the Pick Devices (P) menu. 2. Proteus Simulation Circuit
The ZMPT101B module in Proteus typically features the following pins:
AC Input Pins: Connected to an AC Voltage Source (e.g., VSOURCE) to simulate the 220V/110V mains. VCC & GND: Connected to a +5V DC source and ground.
OUT: The analog output pin connected to an Arduino analog pin (e.g., A0) for measurement. 3. Arduino Code for Simulation
To process the sensor's signal in your simulation, use a library such as the ZMPT101B Arduino Library by Abdurraiq Bachmid.

How to Add Arduino UNO Library to Proteus | Step-by-Step Guide
Here’s a good feature breakdown of a ZMPT101B library for Proteus — useful for simulating AC voltage measurement without real hardware.
If you need, I can also guide you to where to find such a library (e.g., Proteus library forums, GitHub, or how to create a simple one using a Laplace block).
The ZMPT101B module essentially consists of a Voltage Transformer and a Burden Resistor. It steps down high voltage (up to 250V AC) to a low, measurable AC voltage (usually around 2.5V AC riding on a DC offset).
To build this in Proteus, follow these steps:
Before diving into the library, let’s understand the hardware we are simulating.
Use a comparator (LM393) connected to the ZMPT101B output. When the scaled voltage exceeds a threshold (e.g., 3V representing 250V AC), trigger a virtual relay and disconnect the load.

If nothing appears, you may need to manually add the library path:
Proteus’s default library contains generic components like VSINE (voltage source), OPAMP, and TRANSFORMER. However, the ZMPT101B is a complete module:
A dedicated library provides a parametrized model that mimics real behavior. You can adjust:
Without this library, you are essentially flying blind. With it, you can run accurate closed-loop simulations.
