UV Exposure Dose Accumulator Kit with Arduino Nano + Sensor
Build a Personal UV Exposure Dose Accumulator with Arduino Nano – Track Your Daily Sun Safety
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You’ll assemble a compact device that reads UV intensity from the ML8511 sensor, accumulates daily UV dose using an Arduino Nano and real-time clock, and warns you with a buzzer when you approach 80% of the safe limit recommended for your skin type. Perfect for outdoor enthusiasts, school science projects, or anyone curious about sun safety.
What You'll Build
A portable UV exposure monitor that tracks your cumulative daily dose, displays the percentage of safe exposure on a bright OLED screen, and sounds an alert at 80% usage. The DS3231 RTC ensures accurate daily reset at midnight, and the whole system runs on a 9V battery.
What You'll Learn
- Calibrating an analog UV sensor and converting voltage to UV index
- Programming an Arduino Nano to log and accumulate sensor data over time
- Interfacing an I2C OLED display and real-time clock module
- Implementing threshold-based alarms with an active buzzer

Who This Kit Is For
Students in CBSE Class 11-12 pursuing physics practicals or computer science projects, B.Tech ECE/EEE undergraduates looking for a sensor-based mini project, and participants in Smart India Hackathon teams needing a wearable health-monitoring prototype. Also ideal for ATL Tinkering Lab students exploring environmental sensing.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to access the AI companion; it can walk you through code debugging, wiring checks, and sensor calibration. For additional help, WhatsApp us and an engineer will respond within hours.
Can I use this kit to measure UV exposure indoors?
The ML8511 sensor is designed for outdoor UV (sunlight) detection; indoor fluorescent lighting produces negligible UV and won't give meaningful readings. Use it outdoors or near windows for best results.
How do I interpret the 80% alarm?
The alarm triggers when the total daily UV dose reaches 80% of a conservative safe limit for fair skin (about 20 minutes of peak sun). You can adjust the threshold in the code to match your skin type or local solar conditions.
What if I need to add Bluetooth to log data wirelessly?
The Arduino Nano does not have built-in Bluetooth, but you can extend the project by adding an HC-05 module to the breadboard. Our AI companion can guide you through the integration steps.
ML8511 UV sensor accumulates daily UV dose and displays safe percentage used. Buzzer warns at 80%.
