Arduino UV Sensor Tutorial | Measure Ultraviolet Light Index with Arduino
Monitor UV radiation levels with an Arduino UV sensor. This tutorial shows you how to wire up a UV sensor module, read UV index values, and build a portable sunburn-warning device or outdoor UV monitor.
☀️ What you'll learn:
• How UV sensors measure ultraviolet radiation
• Wiring a UV sensor (GUVA-S12SD or ML8511) to Arduino
• Converting raw readings to a UV index value
• Project ideas: UV index meter, sunscreen reminder, plant UV monitor
