Ks0204 keyestudio GUVA-S12SD 3528 Ultraviolet Sensor

Introduction

keyestudio GUVA-S12SD 3528 Ultraviolet Sensor is used to detect ultraviolet light. It includes GUVA-S12SD, applied to measure ultraviolet index of intelligent wearable device, such as watches,smart phone and outdoor device with UV index detecting. It still is used to monitor the intensity of ultraviolet light and as a UV flame detector when disinfecting things by ultraviolet light.

Connection Diagram

Sample Code

/*
  AnalogReadSerial
  Reads an analog input on pin 0, prints the result to the serial monitor.
  Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

 This example code is in the public domain.
 */

// the setup routine runs once when you press reset:
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:
  int sensorValue = analogRead(A0);
  // print out the value you read:
  Serial.println(sensorValue);
  delay(1);        // delay in between reads for stability
}

Result

After wires are connected, upload the program; when power on, open serial monitor displaying data showed as following picture.

Shine UV lamp to the sensor, and the data on serial monitor is changing showed as following picture.
