Two common measurement goals:
If you’ve ever worked with an Arduino or ESP32 to measure mains AC voltage, you’ve probably come across the —a popular, inexpensive AC voltage sensor module. It’s great for DIY energy monitors, smart plugs, and overvoltage protection systems. zmpt101b library for proteus
float readACvoltage() int raw = analogRead(A0); float voltage = (raw / 1023.0) * 5.0; // ADC to voltage // Convert output voltage back to primary AC (calibration required) float rms = (voltage - 2.5) * scaleFactor; return rms; Two common measurement goals: If you’ve ever worked
Example pseudocode (concise):
