You might have heard about LoRaWAN, a network of connected nodes with gateways, brokers and more. If this is too complicated for you, you do not have an internet connection, or if you do not want to depend on other’s infrastructure this video is for you: Today, we will build a point-to-point connection using two plain LoRa modules. And of course we will check out the range of this connection. In the end, I will know when the postman put the nice packets from China into my mailbox. Without going into the freezing winter weather.

Today
- We will build two lovely LoRa nodes, one with an Arduino and one with an ESP8266
- The Arduino LoRa node will be the sender of sensor data
- The Wemos node will act as a receiver of the data.
- It will also get an MQTT connection to node-red
- We will take some precautions against lousy communication conditions and implement a feedback mechanism
- We will do some range testing of this LoRa connection
- We will learn about reducing the power consumption of Arduino boards using…
