Specifications

• Signal Type: Analog Output
• Operating Voltage: 3.3V - 5V DC
• Test Accuracy: ±1 UVI
• Response Wavelength: 200nm - 370nm
• Operating Current: Typical 0.06mA, Maximum 0.1mA
• Module Dimensions: 19.8mm x 15mm

Pinout

• VCC: Positive power supply input (3.3V - 5V)
• GND: Ground
• OUT: Analog signal output (connect to an analog input pin on your microcontroller)

Connecting the Sensor

1. VCC: Connect to the 3.3V or 5V power supply of your microcontroller.
2. GND: Connect to the ground of your microcontroller.
3. OUT: Connect to an analog input pin on your microcontroller.

Usage Notes

• For Arduino users: Ensure that the analog input pin connected to OUT is properly configured to receive analog signals.
• For other microcontrollers (e.g., ARM-based boards): Set the corresponding I/O pin to input mode/receive mode.
• Important: Failure to configure the I/O pin as an input may result in the sensor not functioning correctly.

Example Code

Here’s a simple example of how to read the UV index from the sensor using an Arduino:

const int uvPin = A0; // OUT pin connected to analog pin A0

void setup() {
  Serial.begin(9600);
}

void loop() {
  int uvLevel = analogRead(uvPin);
  float voltage = uvLevel * (5.0 / 1023.0); // Convert the analog reading to voltage
  float uvIndex = mapVoltageToUVIndex(voltage); // You may need to create a function based on the sensor's characteristics
  Serial.print("UV Index: ");
  Serial.println(uvIndex);
  delay(1000);
}

// Placeholder function for mapping voltage to UV index
float mapVoltageToUVIndex(float voltage) {
  // Implement the mapping based on the sensor's datasheet
  return voltage * calibrationFactor;
}

Note: The calibration factor should be determined based on the sensor’s datasheet or by calibration with known UV index levels.
