Voltage Sensor Proteus Library Guide

Mastering Power Monitoring: The Ultimate Guide to the Voltage Sensor Library in Proteus

Electrical Implementation (recommended netlist/subcircuit)

Provide a SPICE subcircuit that models attenuation, protection, and filtering. Example parameter list:

• R1, R2 — voltage divider (sets Vout = VIN * R2/(R1+R2))
• Rs — series resistor for input/current limiting
• D1, D2 — clamp diodes to Vout rail and ground
• C1 — input/output filter cap
• Rout — output source impedance (small, e.g., 100 Ω)

Behavioral/idealized elements can be used for simplified linear scaling; include temperature/offset parameters if needed. voltage sensor proteus library

1. Use Existing Built-in Components

Proteus has generic voltage probes and meters: Mastering Power Monitoring: The Ultimate Guide to the

• DC VOLTMETER – Search in Simulator Primitives → DC Voltmeter
• VOLTAGE PROBE – From Virtual Instruments mode
• Resistor divider + ADC – Simulate a voltage sensor using an ADC pin (e.g., ADC0804)

Output Waveform:

• The voltage sensor outputs a DC level proportional to RMS (slow).
• The comparator output goes high every time AC crosses 0V (50Hz = pulse every 10ms).
