Extract the zip file. You should see two types of files: .lib and .idx . Step 2: Copy the Files
Click on the (or press the 'P' button) to open the "Pick Devices" window.
Connect the high-voltage DC source to the input terminals ( VCC and GND of the sensor's high side). Connect the output interface pins: VOUT pin →right arrow Arduino Analog Input pin A0 . GND pin →right arrow Arduino GND . Arduino Code Structure

A physical DC voltage sensor module is essentially a voltage divider circuit utilizing a 10kΩ and a 7.5kΩ resistor. It scales down an input voltage (up to 25V) to a 0-5V range suitable for an Arduino analog pin. Setting Up the Circuit voltage sensor proteus library
Pre-calibrated internal code models that streamline the simulation process without manual math errors. How to Download and Install a Voltage Sensor Library
Most downloadable "voltage sensor libraries" for Proteus are actually combining E devices with clamping diodes (to protect ADC from over-voltage).
In the physical world, a standard voltage sensor module (like the 0-25V sensor for Arduino) is simply a . It uses two resistors (typically 30KΩ and 7.5KΩ) to scale down a high voltage to a 0–5V range that a microcontroller's Analog-to-Digital Converter (ADC) can safely read. In Proteus, you have three primary ways to replicate this:
Press on your keyboard to open the "Pick Devices" dialog box. Type Voltage Sensor in the keywords search bar. Extract the zip file
your Proteus desktop shortcut and select Open file location .
Simulating voltage measurements is a core requirement for projects involving microcontrollers, smart grids, and power electronics. Proteus Design Suite does not always include a dedicated, real-world visual voltage sensor module (like the popular ZMPT101B or standard DC voltage divider modules) in its default installation.
Because the hardware scales the voltage by a factor of 5, your microcontroller code must invert this calculation to display the true voltage value:
Labeled as S (Signal), + (5V power), and - (GND) for connection to the microcontroller. How to Install the Voltage Sensor Library Connect the high-voltage DC source to the input
This is the most common category for hobbyist projects, especially with Arduino. These modules are essentially simple voltage dividers that allow a microcontroller to measure higher voltages than its logic level (e.g., 5V or 3.3V).
When you open Proteus ISIS, the default library contains thousands of components, but . Instead, you will find:
It reduces higher input voltages (up to 25V) to a range (0–5V) that a microcontroller like an Arduino can safely read through its analog pins.
GitHub hosts numerous collections of Proteus libraries. For example, the repository by Karan‑nevage includes libraries for flame sensors, gas sensors, infrared sensors, soil moisture sensors, ultrasonic sensors, and many more. Although it does not list a generic voltage sensor, it provides an excellent starting point for building a comprehensive sensor simulation environment.
