Grove – UV Sensor

The Grove – UV Sensor is used for detecting the intensity of incident ultraviolet(UV) radiation. This form of electromagnetic radiation has shorter wavelengths than visible radiation. It is based on the sensor GUVA-S12SD.It has a wide spectral range of 200nm-400nm. The module will output electrical signal which is varied with the change of the UV intensity. UV sensors are used for determining exposure to ultraviolet radiation in laboratory or environmental settings.
Features
  • High stability
  • Good Sensitivity
  • Low power consumption
  • Schottky type photodiode sensor
  • Wide response range
  • Grove Interface

Introduction

The Grove – 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 Grove – 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.

Usage

UV sensors are used in many different applications. Examples include pharmaceuticals, automobiles, and robotics. UV sensors are also used in the printing industry for solvent handling and dyeing processes. In addition, UV sensors are also used in the chemical industry for the production, storage, and transportation of chemicals.

The fact of the UV sensor work is: In sunlight, the UV index and Photocurrent are a linear relationship.

About our Grove – UV Sensor, we have converted Photocurrent to corresponding voltage value collected by Arduino/Seeeduino. The output voltage and the UV index is linear:

illumination intensity = 307 * Vsig

where:
Vsig is the value of voltage measured from the SIG pin of the Grove interface, unit V.
illumination intensity unit: mW/m2 for the combination strength of UV light with wavelength range: 240nm~370nm

Note: To calculate the UV index value, please refer to http://www2.epa.gov/sunwise/uv-index. It’s hard to say that the measurement from this sensor can be converted to the EPA standard UV index, but can be estimated roughly.

UV Index = illumination intensity / 200

Example

  • Connect it to A0 port of Grove – Base Shield.
  • Plug the Grove – Base Shield into Arduino/Seeeduino and connect them to PC using a USB cable.
  • The demo code as show below.
 
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");
 
}
