Zmpt101b Voltage Sensor Library For Proteus Work -

The answer is and a reliable ZMPT101B library .

#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) zmpt101b voltage sensor library for proteus

// Remove DC offset and convert to RMS float peakVoltage = (maxV - Vref) * (120.0 / 0.6); // Calibration factor voltageRMS = peakVoltage / 1.414; The answer is and a reliable ZMPT101B library

void setup() lcd.begin(16, 2); lcd.print("AC Voltage:"); float voltageRMS = 0

delay(500);

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?
