Visualize Temperature & Humidity with Raspberry Pi Pico W DHT11 — Build an IoT Prototype with Miniviz

This guide demonstrates how to wire a DHT11 temperature/humidity sensor to a Raspberry Pi Pico W, read sensor data using MicroPython, and send it to the Miniviz platform for visualization. It covers the full workflow from hardware setup and firmware installation through coding a data collection script and posting readings via HTTP to build a complete IoT prototype.
