ตัวอย่างโคด 

int UVsensorIn = A0; //Output from the sensor
void setup()
{
pinMode(UVsensorIn, INPUT);
Serial.begin(9600); //open serial port, set the baud rate to 9600 bps
}
 
void loop()
{
int uvLevel = averageAnalogRead(UVsensorIn);
float outputVoltage = 5 * uvLevel/1024;
float uvIntensity = mapfloat(outputVoltage, 0.99, 5.0, 0.0, 15.0);
 
Serial.print(" UV Intensity: ");
Serial.print(uvIntensity);
Serial.print(" mW/cm^2");
Serial.println();
delay(200);
}

Output

Open the serial monitor and you should see something which looks like this

UV Intensity: 0.27 mW/cm^2
UV Intensity: 0.30 mW/cm^2
UV Intensity: 0.30 mW/cm^2
UV Intensity: 0.27 mW/cm^2
UV Intensity: 0.30 mW/cm^2
UV Intensity: 0.27 mW/cm^2
UV Intensity: 0.30 mW/cm^2
UV Intensity: 0.30 mW/cm^2
UV Intensity: 0.30 mW/cm^2

UV Sensor Board ML8511 For Arduino GY-8511 ML8511 Ultraviolet Module Transducer ML8511 UV Rays Sensor Breakout Module Detector 

The ML8511 breakout is an easy to use ultraviolet light sensor. The MP8511 UV (ultraviolet) Sensor works by outputing an analog signal in relation to the amount of UV light that’s detected. This breakout can be very handy in creating devices that warn the user of sunburn or detect the UV index as it relates to weather conditions.

This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB (burning rays) spectrum and most of the UVA (tanning rays) spectrum. It outputs a analog voltage that is linearly related to the measured UV intensity (mW/cm2). If your microcontroller can do an analog to digital signal conversion then you can detect the level of UV!
