Overview

In this project, we're going to build a small weather-logging node using a Feather and a temperature sensor. The captured data will then be sent to The Things Network.

What is The Things Network?

The Things Network is a project dedicated to building a network for the Internet of Things. While WiFi is used in most Internet of Things devices, The Things Network uses a protocol called LoRaWAN which allows devices to talk to the internet without cellular or WiFi connectivity. This means you don't need to worry about protected wireless hotspots, cellular data plans, or spotty WiFi connectivity. 

It's ideal for most internet of things projects, and unlike cellular plans or WiFi - it's free to use.

Also, there are plenty of gateways available to connect your feather to - if you'd like to find a gateway in your area, check the Gateway Map.

Parts

We're going to use one of our RadioFruits, the Feather M0 LoRa. In The The Things Network terms, this will be used as our device.
