UV Intensity Measurement with ML8511

Introduction

This experiment shows how to measure ultraviolet (UV) intensity using the ML8511 sensor.

Components Needed

• ML8511 UV Sensor
• Arduino
• Jumper Wires

Circuit Setup

1. Connect the VCC pin of the ML8511 to 5V on the Arduino.
2. Connect the sensor's analog output pin to an analog input pin (e.g., A0) on the Arduino.

The sensor will measure the UV intensity, and the Arduino will process and display the data.

Code for UV Intensity Measurement

Upload the following code to your Arduino to measure UV intensity:

const int uvPin = A0;

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

void loop() {
  int uvLevel = analogRead(uvPin);
  Serial.print("UV Intensity: ");
  Serial.println(uvLevel);
  delay(1000);
}
            

Explanation

The ML8511 sensor detects UV light intensity, which is read by the Arduino and displayed on the Serial Monitor.

Troubleshooting

• Ensure the sensor is positioned in an area exposed to UV light.
• If readings are too low, verify sensor connections and check for power supply issues.
