Arduino Uno UV Sensor Starter Kit — Build a UV Index Monitor for 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.

This kit lets young makers build a real UV index monitor that lights up an LCD with readings and a safe/caution status. It’s a hands-on way to learn about ultraviolet light, sensor data, and how to protect yourself from sun exposure — all while mastering Arduino basics through a project that actually matters outdoors.

What You'll Build

You’ll wire up the ML8511 UV sensor to an Arduino Uno, connect a 16x2 LCD with I2C backpack, and code it to display the UV Index in real time. When sunlight hits the sensor, the screen shows the index number and clearly says “Safe” or “Caution” so you know whether to wear sunscreen or stay indoors.

What You'll Learn

• Read analog sensor values from the ML8511 UV sensor and convert them to UV Index
• Interface a 16x2 LCD with I2C backpack to show text and numbers
• Write Arduino code to compare UV levels against safe thresholds and trigger status messages
• Troubleshoot sensor and display circuits on a breadboard
