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:

Installing a custom .TEF and .LBK (or .IDX and .LIB ) library file that provides a pre-packaged sensor block with clear input/output pins. 2. How to Download and Install a Voltage Sensor Library voltage sensor proteus library

Press on your keyboard to open the "Pick Devices" dialog box. Type Voltage Sensor in the keywords search bar.

If you do not have a custom ZMPT101B library file, you can build an equivalent circuit in Proteus:

const int sensorPin = A0; float vInput = 0.0; float vOutput = 0.0; // Adjust these values based on your sensor's specific resistor values float R1 = 30000.0; float R2 = 7500.0; void setup() Serial.begin(9600); void loop() int rawValue = analogRead(sensorPin); // Convert raw digital value back to sensor output voltage vOutput = (rawValue * 5.0) / 1024.0; // Calculate original input voltage using the inverse voltage divider formula vInput = vOutput / (R2 / (R1 + R2)); Serial.print("Measured Voltage: "); Serial.concat(vInput); Serial.println(" V"); delay(500); Use code with caution. Troubleshooting Simulation Errors Connect a variable DC voltage source (or a

Proteus Design Suite is an invaluable tool for testing electronic circuits before physical fabrication. However, simulating voltage measurements often puzzles beginners because Proteus does not include a physical-looking "voltage sensor module" (like the common Arduino blue voltage sensor) in its default installation.
