Zmpt101b Voltage Sensor Library For Proteus May 2026

// Remove DC offset and convert to RMS float peakVoltage = (maxV - Vref) * (120.0 / 0.6); // Calibration factor voltageRMS = peakVoltage / 1.414;

Have you used a different AC voltage sensor in Proteus? Let me know in the comments below! zmpt101b voltage sensor library for proteus

Simulating AC mains voltage safely is a nightmare for most hobbyists. One wrong probe, and your $50 USB oscilloscope is toast. Enter the ZMPT101B —a popular, isolated AC voltage sensor module. But how do you test your Arduino or ESP8266 code without frying real hardware? // Remove DC offset and convert to RMS

void setup() lcd.begin(16, 2); lcd.print("AC Voltage:"); One wrong probe, and your $50 USB oscilloscope is toast

#include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 2); float voltageRMS = 0; float readValue = 0; float Vref = 2.5; // Output offset of ZMPT101B (adjust based on simulation)

void loop() // Sample multiple times to find peak float maxV = 0; for(int i=0; i<200; i++) readValue = analogRead(A0); // 0-1023 float voltage = (readValue / 1023.0) * 5.0; // Convert to 0-5V if(voltage > maxV) maxV = voltage; delayMicroseconds(100);
