Overview

Harness the power of nature with your PyPortal by building an internet-connected Weather Station!

This guide will guide you through building an internet-connected weather station, complete with sensors to measure everything from the wind speed to the amount of volatile organic compounds which are present in the air. 

This weather-station doesn't just display temperature on the PyPortal's 3.2″ 320 x 240 color TFT screen - it also wirelessly sends data to Adafruit IO for real-time visualization and logging using the easy-to-use Adafruit IO CircuitPython library.

Adafruit IO

Adafruit IO is the easiest way to stream, log, and interact with your data. It's built from the ground up to be easy to use - we do the hard stuff so you can focus on the fun stuff.

Data such as relative humidity and light levels can be hard to visualize and quantify - Adafruit IO makes it simple. Send IO your data and it can store the data for up to thirty days. Want to visualize it? Display your data using Blocks such as charts, graphs, gauges, and more!

CircuitPython Code

Adafruit's CircuitPython is great for building Internet-of-Things projects. Using the Adafruit IO CircuitPython module, you can easily send data to Adafruit IO, receive data from Adafruit IO, and easily manipulate data with the powerful Adafruit IO API.

You can rapidly update your code without having to compile and store WiFi and API secret keys on the device. This means that there's no editing code and re-uploading whenever you move the PyPortal to another network - just update a file and you're set. 

Prerequisite Guides
