Description:

 

The Voltage 230V AC Mains Volt Sensor Module ZMPT101B is an electronic module designed to measure the voltage of an AC power supply. The module features an onboard precision micro voltage transformer and an operational amplifier circuit for high-precision voltage measurements. The voltage input range of the module is 80-260V AC, and it outputs a corresponding voltage signal in the range of 0-5V DC, which can be used for further processing or display. The module has three pins: VCC, GND, and OUT. The VCC and GND pins are used to power the module, while the OUT pin is the signal output pin that provides a voltage signal proportional to the measured AC voltage. To use the module, the VCC and GND pins are connected to a 5V power supply, and the OUT pin is connected to an analog input pin on a microcontroller or other device. The voltage signal from the module can then be read and processed by the microcontroller to determine the AC voltage level. The ZMPT101B module is commonly used in projects that require precise voltage measurements, such as home automation, power monitoring, and industrial control systems. It is also used in the design of voltage regulators, inverters, and power supplies.

 

Principle of Work: 

The ZMPT101B works by using a voltage transformer to step down the AC voltage being measured to a lower voltage that can be easily measured by the operational amplifier circuit on the module. The input voltage is applied to the primary winding of the voltage transformer, which induces a voltage in the secondary winding. The secondary voltage is proportional to the primary voltage and is stepped down by the transformer's turn ratio. The output of the transformer is connected to the input of the operational amplifier circuit, which is designed to accurately measure and sample the voltage signal. The operational amplifier circuit uses an appropriate compensation and amplification circuit to ensure that the output signal is accurate and stable, despite variations in the input signal. The output of the operational amplifier circuit is then connected to the OUT pin on the module, which provides a voltage signal that is proportional to the measured AC voltage level. This output signal can be read and processed by a microcontroller or other device to determine the AC voltage level and perform any necessary control or monitoring functions.

 Connect the circuit as you see in the scheme and be careful when dealing with AC power, you can work without the fuze but it is better for your safety:

 

Library:

No library Needed

         

Code: 

code to monitor the AC power using the ZMPT101B module and Arduino:

const int VOLTAGE_PIN = A2; // Connect the OUT pin of the ZMPT101B module to A2 pin on Arduino
float voltageValue = 0;

void setup() {
  Serial.begin(9600); // Initialize the serial monitor
}

void loop() {
  voltageValue = analogRead(VOLTAGE_PIN); // Read the voltage value from the module
  voltageValue = voltageValue * (5.0 / 1023.0); // Convert the ADC value to voltage
  voltageValue = voltageValue * 0.707; // Calculate the RMS voltage value
  Serial.print("Voltage Value (Vrms): "); // Print the voltage value to the serial monitor
  Serial.println(voltageValue, 2); // Print with 2 decimal places
  delay(500); // Wait for 500 milliseconds
}

This code reads the voltage value from the ZMPT101B module and converts it to an RMS voltage value. It then prints the voltage value to the serial monitor with 2 decimal places. The delay function is used to wait for 500 milliseconds between each reading.

Note: Be sure to take appropriate safety measures when working with high-voltage AC power. It is recommended to use a transformer to step down the voltage to a safe level before connecting the ZMPT101B module to the power supply.
