Build a Rain Alert System with the Micro:bit Smart Umbrella Reminder Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a tiny gadget that senses a drop in air pressure before the rain starts and flashes a friendly umbrella icon on its LED display. With the BBC Micro:bit and a BMP280 atmospheric pressure sensor, this kit transforms that idea into a real, working device that your child can build in a single afternoon. It’s the perfect introduction to weather sensing, coding, and electronics for curious young minds.

What You'll Build

Your child will assemble a portable weather companion. The BMP280 sensor continuously checks air pressure, and when it detects a sharp fall — a classic sign of approaching rain — the micro:bit springs into action. It scrolls “Take Umbrella” and pulses a bright umbrella symbol across the 5x5 LED grid. The entire device runs on AA batteries, so it can be clipped to a backpack or kept by the front door for a daily reminder.

What You'll Learn

• How atmospheric pressure changes signal weather shifts, and why a pressure drop often means rain is on the way
• Reading precise sensor data from a BMP280 using the micro:bit’s edge connector pins
• Programming MakeCode blocks to compare pressure readings and trigger visual alerts with conditional “if-then” logic
• Breadboarding and making reliable electrical connections with crocodile clips and jumper wires

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for children aged 8–10 who love discovering how the world works. It fits neatly into CBSE Class 4–5 science explorations, ATL Tinkering Lab sessions that introduce sensor-based projects, and parent-child weekend maker activities. No prior coding experience is needed — the drag-and-drop MakeCode editor makes programming feel like a puzzle.

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.
