• 220 V Voltage Detection
• PLC Compatible

What it is for

This module is ideal for applications requiring electrical isolation between a circuit and a 220 V power line, such as voltage monitoring systems, home alarms, industrial device control, and much more. PLC compatibility expands its usage possibilities in automatic and control contexts.

Tutorial: How to Use 220V Photo Coupler Module

The 220V optocoupler module is ideal for makers who want to electrically isolate their circuit from 220V power lines. It is particularly useful for monitoring voltage presence in industrial or domestic environments, ensuring safety and data integrity.

What you need

• Arduino Uno or similar
• USB Connection
• 5V Power Supply

Steps

1. Connect the optocoupler module to the 220V circuit as specified in the datasheet.
2. Connect the module’s output to a digital input of the Arduino.
3. Write an Arduino sketch to read the state of the input.
4. Verify that the Arduino is correctly reading the state of the module.
5. If necessary, adjust the connections to obtain a correct reading.
6. Implement the software logic to manage the module’s input.
7. Test the system under conditions of 220V voltage presence and absence.
8. Document the results and improve the system if necessary.

Example code

void setup() {
  pinMode(2, INPUT);
  Serial.begin(9600);
}

void loop() {
  int stato = digitalRead(2);
  Serial.println(stato);
  delay(1000);
}

Mini project
