MQTT Weather Dashboard

Cloud · Board: Pi Pico · Day 91 of 100

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.
