GUVA-S12SD Sunshine ultraviolet radiation sensor for Arduino

1. Introduction

GUVA-S12SD ultraviolet sensor is used to detect ultraviolet light, applied to

measure ultraviolet index of intelligent wearable device, such as watches, smart

phone and outdoor device with UV index detecting.

It can be also used to monitor the intensity of ultraviolet light or used as a UV

flame detector when disinfecting things by ultraviolet light.

2. Parameters

 Working voltage: 5V 

 Working current: 50MA 

4. Test Code int sensorPin =A0 ; int value = 0; //define the analog port A0 //set value to 0 void setup() { Serial.begin(9600);//Set baud rate } void loop() { value = analogRead(sensorPin); Serial.println(value, DEC); delay(100); //Set value to the read value of A0 //diaplay value and enter a new line //delay in 0.1S } 5. Test Result： After the line is connected, upload the program code, then open the serial monitor and set the baud rate to 9600.
