UV Ultraviolet Radiation Ray Detection Sensor Module

Description:
The UV Sensor is used for detecting the intensity of incident ultraviolet(UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation. The UV Sensor is based on the sensor GUVA-S12D which has a wide spectral range of 200nm-400nm. The module outputs electrical signal which varies with the UV intensity, which gives your suggestion if it is a good idea to beach today.

Demo:
 void setup()
 {
 Serial.begin(9600);
 }
 void loop()
 { 
 int sensorValue;
 long  sum=0;
 for(int i=0;i<1024;i++)
 { 
 sensorValue=analogRead(A0);
 sum=sensorValue+sum;
 delay(2);
 }  
 sum = sum >> 10;
 Serial.print("The voltage value:");
 Serial.print(sum*4980.0/1023.0);
 Serial.println("mV");
 delay(20);
 Serial.print("\n");
 }
