ZMPT101B is an Arduino library that can be used for:

• Calibration of ZMPT101B module
• AC voltage reading

1. Calibration of ZMPT101B Module:

#include <ZMPT101B.h>

// ZMPT101B ac_sensor(pin,freq)

// pin: arduino pin connected to ZMPT101B module

// freq: AC Frequency in MHz

ZMPT101B ac_sensor(A0,50);

void setup()

{

Serial.begin(9600);

ac_sensor.calibrate(220);

}

void loop(){}

2. Get calibration parameters from Serial:

switch off source

Measure at 0 V => 0.11

switch on source...

Measure at 220.00 V => 81.56

Calibration is done:

a = 2.70, b = -0.30

3. Read voltage:

#include <ZMPT101B.h>

// ZMPT101B ac_sensor(pin,freq)

// pin: arduino pin connected to ZMPT101B module

// freq: AC Frequency in MHz

ZMPT101B ac_sensor(A0,50);

void setup()

{

Serial.begin(9600);

ac_sensor.set(2.70, -0.30);

}

void loop(){

Serial.print(ac_sensor.get_ac();

Serial.println(" Volt"))

Delay(1000); }
