LM016L (16x2 LCD display) or virtual serial terminal Tools: VOLTMETER (AC), OSCILLOSCOPE Wiring Instructions High Voltage Side (Input): Connect the ALTERNATOR terminals to the input pins ( VINcap V sub cap I cap N end-sub GNDcap G cap N cap D ) of the ZMPT101B module.

The physical ZMPT101B module contains a miniature voltage transformer, a sampling resistor, and an multi-turn trim potentiometer connected to an on-board operational amplifier (LM358). It takes a high-voltage AC mains input (e.g., 110V or 220V) and steps it down to a safe, low-voltage AC/DC offset analog signal (0V to 5V) that an Analog-to-Digital Converter (ADC) can safely read.

A dedicated library provides a that mimics real behavior. You can adjust: zmpt101b library for proteus

: Close and reopen Proteus to refresh the component database. You can then find it by searching for "ZMPT101B" or "voltage sensor" in the Pick Components window. Using the Sensor in Simulations

To simulate this sensor, you typically need to download and manually install custom library and model files:

Once the software reboots, you can easily pull the device into your simulation schematic capture window. #define SENSOR_PIN A0 const float FACTOR = 0

Note: The ProgramData folder is hidden by default in Windows. Enable "Hidden items" in the File Explorer View tab to see it. Step 3: Verify the Installation Open Proteus and launch . Press P on your keyboard to open the "Pick Devices" window. Type ZMPT101B into the keywords search box.

You can find the library file ( .IDX and .LIB ) on:

Incorrect wiring in a physical setup can instantly destroy your Arduino or laptop; simulations eliminate this risk.

Double-click the alternator to edit its properties. Set the Amplitude to (which yields ~220V RMS) or 170V (for ~120V RMS), and set the Frequency to 50Hz or 60Hz based on your regional grid standards.
