How to calculate UV Index

The module has an analog output and varies approximately between 0 and 1 volt. The output voltage of this module varies in accordance with the intensity of UV light according to the following diagram.

You can see the accurate value of UV intensity according to output voltage in the image below.

Each level of UV intensity represents the causative factor. The image below shows what each level includes:

 

UVM30A UV Sensor Module Pinout

This module has 3 pins:

  1. VCC: Module power supply – 3V to 5V

  2. GND: Ground

  3. OUT (SIG): Output analog signal – varies from 0-1 V

 

Interfacing UVM30A UV Sensor Module with Arduino

Step 1: Circuit

The following circuit shows how you should connect Arduino to UV sensor. Connect wires accordingly.

 

Step 2: Code

Upload the following code to your Arduino.

   /*
  UVM30A-UV-Module

*/
void setup(){
  Serial.begin(9600);
}

void loop()
{ 
  int sensorValue;

 sensorValue=analogRead(A0);
Serial.print("The voltage value:");
Serial.print(sensorValue*5000/1023.0);
Serial.println("mV");
delay(1000);
Serial.print("\n");
}

 

We want to display the output in millivolts on the Serial Monitor. So, we first save the analog input and convert its range to 0 to 1000 in millivolts.

By bringing the camera flashlight of your mobile phone close to the sensor, the output changes in millivolts as shown below.
