# MQTT Weather Dashboard

Day 91 of the 100 Days 100 IoT Projects collection. Board: Pi Pico.

DHT11 readings travel over MQTT into a Node-RED dashboard, optionally via Oracle Cloud. Full pipeline from sensor to cloud chart.

## How it works

DHT11 readings leave the Pico as MQTT messages, flow through the broker into Node-RED, and land on dashboard charts — optionally relayed through Oracle Cloud. One pipeline from a two-dollar sensor to a cloud chart, with every hop visible and debuggable.

## What you'll learn

- End-to-end MQTT pipeline
- Cloud charting
- Sensor-to-dashboard flow
- Multi-hop IoT architecture
