3. POTENTIOMETER as Variable Voltage Source

  • Simulate variable sensor input using a potentiometer.
  • Wiper connected to ADC pin.
  • Vary pot to test code across voltage range.

Key Takeaways:

  • For basic simulation: use two resistors + ADC.
  • For advanced projects: use third-party ZMPT101B or voltage sensor modules.
  • Always verify scaling factor with calculations.
  • Use virtual instruments (voltmeter, oscilloscope) to debug.

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. Voltage Sensor — Proteus Library Write-up References and

Testing & Validation in Proteus

  1. Place the voltage sensor and a DC voltage source (0–50 V) in the workspace.
  2. Connect VOUT to an ADC/mock microcontroller ADC input or a voltmeter instrument.
  3. Run DC sweep from 0 to max VIN and plot VOUT vs VIN — verify linearity and scale (Vout ≈ Vin/10).
  4. Test transient response using pulse source; inspect rise/fall and filter behavior.
  5. Apply over-voltage pulses to confirm clamp diodes limit Vout safely.

How to Install:

  1. Download the .LIB and .IDX files (usually zipped).
  2. Copy them to the LIBRARY folder inside your Proteus installation (e.g., C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\LIBRARY).
  3. Restart Proteus.
  4. Use the Pick from Libraries button and search for the component name.

The AC Mains Challenge (230V RMS)

Simulating a voltage sensor for mains requires a ZMPT101B model. Since this is not native to Proteus, advanced users build it using:

  • Transformer (TRAN-2P2S) : Step down from 230V to 9V.
  • Precision rectifier (Op-amp LM324 + diodes).
  • Low-pass filter to get average DC proportional to RMS.

Note: Some third-party libraries (see Part 4) include a ready-made ZMPT101B module.
