[Arduino source code for KC868-M16v2]-05 simple usage detect AC voltage

Code:

/**

 * This program shows you how to use the basics of this library.

#include <ZMPT101B.h>



//#define SENSITIVITY 500.0f

#define SENSITIVITY 507.25f



// ZMPT101B sensor output connected to analog pin A0

// and the voltage source frequency is 50 Hz.

  // Change the sensitivity value based on value you got from the calibrate

  // example.

  // read the voltage and then print via Serial.

  float voltage = voltageSensor.getRmsVoltage();

  Serial.println(voltage);
