In this new project, we’re going to learn how to get connected to The Things Network by building a small weather node only using a Feather M0 LoRa and a DHT22.
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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
