UV Sunscreen Effectiveness Test Kit with Arduino Uno + Sensor
Build a UV Sunscreen Effectiveness Tester with Arduino Uno & ML8511 Sensor
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your understanding of sun protection into a working scientific instrument. With this kit, you’ll build a handheld UV meter that reads ambient ultraviolet radiation through a sunscreen-coated surface and automatically calculates the percentage blocked—simulating how SPF ratings are tested. No prior electronics experience needed; every wire, sensor, and code library is ready for you.
What You'll Build
You’ll assemble an Arduino-powered tester that displays live UV index on a crisp 16x2 LCD. Place a clean glass slide with sunscreen between the UV source and the ML8511 sensor, and watch the numbers change. The Arduino sketch converts raw voltage to UV intensity, compares readings before and after sunscreen application, and outputs a protection percentage you can interpret as an SPF indicator. The result is a compact, reusable device perfect for science fair exhibits or classroom demonstrations.
What You'll Learn
- Interfacing the ML8511 UV sensor with Arduino Uno and reading analog voltage
- Converting sensor output into meaningful UV index and SPF-like values
- Configuring I2C communication to drive the 16x2 LCD without messy wiring
- Structuring a real-world scientific experiment with controlled variables

Who This Kit Is For
This kit is designed for CBSE students (Class 6–12) exploring environmental physics or computer science projects, ATL Tinkering Lab participants prototyping health-tech ideas, and first-year B.Tech ECE/EEE undergraduates needing a quick sensor-data lab. It’s also a smart choice for parents introducing electronics through a real-world experiment that answers a question every child asks: “Does my sunscreen actually work?”
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 inside the box to chat with the AI companion, or drop a message on our WhatsApp support line. We respond the same day with wiring screenshots and code tweaks specific to your issue.
Does this kit really measure SPF accurately enough for a science project?
It delivers a repeatable UV blocking percentage that correlates with sunscreen SPF. The calibration routine adjusts for ambient conditions, making it a reliable tool for comparative experiments and science fair displays.
What do I use as the test surface for sunscreen?
A clean glass or transparent plastic slide works perfectly. Apply a thin, even layer of sunscreen, let it dry, then place it between the UV source and the sensor. The kit includes instructions for consistent sample preparation.
Can I test indoors without sunlight?
Sunlight provides the strongest UV signal, but you can use a UV LED flashlight or a UV lamp. The sensor responds to UV-A and UV-B light, so any source in that range will generate measurable data.
ML8511 measures UV before and after sunscreen. Calculates SPF protection percentage.
