Introduction

This UV Sensor used GUVA-S12SD chip is suitable for detecting the UV raditation in sunlight. It can be used in UV Index Monitoring, DIY project, UV-A Lamp Monitoring, Plants growing Environmental monitoring...etc. It can detect the UV wavelength of 200-370nm, fast response, linear analog voltage signal output. Small size, easy for installing. With the diagram of the world health organization UV index grading standards, you can know the UV index from the sensor directly.

Sample Code

/*
# This Sample code is for testing the UV Sensor .
#Connection:
    VCC-5V
    GND-GND
    OUT-Analog pin 0
*/

void setup()
{
  Serial.begin(9600);// open serial port, set the baud rate to 9600 bps
}
void loop()
{
  int sensorValue;
  int analogValue = analogRead(0);//connect UV sensors to Analog 0
  if (analogValue<20)
  {
    sensorValue = 0;
  }
  else
  {
    sensorValue = 0.05*analogValue-1;
  }
  Serial.println(sensorValue);//print the value to serial
  delay(200);
}
