Pi Pico UV Index Wearable
Pi Pico UV Index Wearable Kit: Build a Sun Safety Tracker That Clips Anywhere
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Sun awareness becomes second nature when you wear your own UV monitor. This kit puts a personal sun safety tracker right on a bag strap, cap, or collar, continuously showing the UV index and counting down safe outdoor time. It’s a practical introduction to sensing, microcontrollers, and battery-powered wearables built on the Raspberry Pi Pico.
What You'll Build
A compact, rechargeable device that reads ultraviolet intensity through the ML8511 sensor, displays the UV index and remaining exposure limit on a bright OLED screen, and fits inside a custom ABS enclosure. Clip it on before heading out, and the Pico Wearable keeps you informed whether you're at a school sports meet, a weekend trek, or simply playing in the park.
What You'll Learn
- How to read an analog UV sensor with the Raspberry Pi Pico’s ADC
- Driving an I2C OLED display to show sensor readings and computed limits
- Battery power management with the TP4056 charging module and a LiPo cell
- Basic soldering and enclosure assembly to create a durable wearable

Who This Kit Is For
Kids aged 10+ who want to build a real gadget with an adult nearby, CBSE Class 11–12 students working on sensor investigatory projects, B.Tech ECE/EEE undergraduates prototyping a wearable, or ATL Tinkering Lab mentors looking for an engaging sun-safety activity. Even parents searching for a weekend STEM project will find clear guidance. This kit also fits neatly into a Smart India Hackathon wearable concept or an IoT health gadget demo.
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 box QR code for the AI build companion, which walks through each step. If you need a human, message us on WhatsApp—real engineers reply within a day.
Is this safe for children to wear outdoors?
Yes. The low‑voltage LiPo battery, fully enclosed ABS case, and smooth edges make it safe once assembled. Adult supervision is recommended for soldering.
How long does the battery last?
The 500mAh cell powers continuous UV monitoring for about 4–5 hours. Recharge via the TP4056 module’s micro USB port.
Do I need prior soldering experience?
Not at all. The included guide shows every joint, and the AI companion highlights exactly where to solder. Beginners pick it up quickly; younger builders just need an adult nearby.
