Voltage Sensor Proteus Library -

Run the simulation. Open Virtual Terminal. You will see:

Battery Voltage: 12.59 V
Battery Voltage: 12.60 V

Change the DC battery to 15V. The voltage sensor output will clamp at 5V, and the serial monitor will show exactly 25.0V (full scale).

A voltage sensor is essentially a voltage divider + ADC. To simulate it:

Cause: Complex third-party models with op-amps or transformers.
Fix: Increase simulation speed in "System → Set Animation Options" or replace with simpler resistor divider. voltage sensor proteus library

Cause: No filtering capacitor in the sensor output. Fix: Add a 10µF capacitor from sensor output to ground inside your library design.

  • Buffer/Isolation (op amp follower or unity-gain buffer)

  • Instrumentation amplifier / differential measurement Run the simulation

  • Voltage-to-frequency / Voltage-to-current transducers

  • ADC front-ends (for microcontroller measurement)

  • Protection and filtering

    • void setup() 
  Serial.begin(9600);

    void loop() 
int adcValue = analogRead(A0);
float voltage = (adcValue / 1023.0) * 5.0; // Voltage at divider output
float inputVoltage = voltage * ((20000 + 5000) / 5000.0); // Rescale
Serial.print("Input Voltage: ");
Serial.print(inputVoltage);
Serial.println(" V");
delay(500);

  • Proteus supports two simulation engines relevant here: analog SPICE (for detailed analog device behavior) and mixed-mode (digital + analog). Voltage sensor parts must be compatible with the chosen engine.

    • Proteus remains one of the best tools for learning and prototyping voltage sensing circuits—provided you understand how to leverage its analog and mixed-signal capabilities. Change the DC battery to 15V
