Introduction
UV radiation from the sun can damage our skin. This increases the risk of skin cancer. However sunlight helps make vitamin D and keeps our body clock running right. Hence it is important to watch how much UV light we get. This article talks about a new wearable device that tracks UV exposure. It warns users when UV levels get too high. It tells them when to use sunscreen or find shade. The device uses sensors, wearable tech, and processes data in real time. It aims to protect our health and teach us about UV risks.
Wearable Technology to detect UV Radiation
Wearable technology in healthcare includes devices worn on the body. They can measure and monitor bodily functions. A useful application of this technology is a UV exposure tracker. It uses UV sensors, microcontrollers, and wireless communication. This device alerts users about their sun exposure as it happens. The project involves electronics, sensor technology, and data communication. Its purpose is to help manage and prevent skin damage from UV radiation.
Core Technologies and Components:
- UV Sensors (UV Index Sensor – GUVA-S12SD): These sensors detect the intensity of UV radiation. They are essential for the UV tracker. They measure the current UV index to which the wearer is exposed.
- The microcontroller, like an Arduino Uno or ESP8266, is the brain of the wearable device. It collects data from the UV sensor. Then, it processes this data. Its job is to figure out if the UV exposure level is safe or not.
- The ESP8266 Wi-Fi Module is a wireless communication module. It lets the device send data to a smartphone or the cloud. This allows for real-time alerts and tracking.
- Battery (Lithium Polymer Battery): Powers the wearable device, ensuring it remains operational without constant charging.
Where to Buy:
You can purchase components online. These include the UV sensor (GUVA-S12SD), Arduino Uno, ESP8266 Wi-Fi Module, and other electronics. Stores like Adafruit, SparkFun, or Amazon sell them. You might also find them at local electronics shops or online stores in your country.
Computer Program
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
// WiFi credentials and Blynk token
char ssid[] = “Your_WiFi_SSID”;
char pass[] = “Your_WiFi_Password”;
char auth[] = “Your_Blynk_Token”;
// Pin where the UV sensor is connected
int uvSensorPin = A0; // Analog input pin that the sensor is attached to
float uvLevel;
int uvIntensity;
void setup() {
Serial.begin(9600); // Start serial communication at 9600 baud
Blynk.begin(auth, ssid, pass); // Initialize Blynk
pinMode(uvSensorPin, INPUT); // Set the UV sensor pin as an input
}
void loop() {
uvLevel = analogRead(uvSensorPin); // read the input on analog pin
uvIntensity = map(uvLevel, 0, 1023, 0, 11); // Convert the analog reading (which goes from 0 – 1023) to a UV index (0 – 11+)
Blynk.virtualWrite(V1, uvIntensity); // Send UV index to Blynk
Serial.print(“UV Level: “);
Serial.println(uvLevel);
Serial.print(“UV Intensity (Index): “);
Serial.println(uvIntensity);
delay(2000); // Wait for 2 seconds between readings
}
Explanation:
- Setup Function: Starts serial communication and connects to Blynk. It sets the UV sensor pin to read input.
- Loop Function: The Loop Function does several tasks. First, it reads the UV sensor. Then, it converts the sensor’s reading to match the UV index scale. After that, it sends this data to the Blynk app. Lastly, it prints the UV index on the serial monitor.
This setup lays the groundwork for using sensor technology in wearable devices. It includes IoT features to improve user interaction and safety. These projects increase understanding of STEM fields. They also show the potential uses of these technologies in the real world.
