 LoRa WAN is the internet-based version of LoRa. While LoRa communication only works between generally two devices, LoRa WAN can communicate between hundreds of devices by the means of a gateway. LoRa WAN consists of end-nodes and at least one gateway. Communication between the gateway and the nodes is bidirectional and based on LoRa radio communication. Refer to the [[LoRa research]] section for more info on how LoRa works and useful tutorials. This section is for on-the-farm system-specific information.

 The master Arduino, also called a server, measures the battery voltage with the [Adafruit INA260](https://www.adafruit.com/product/4226?gclid=Cj0KCQiA4feBBhC9ARIsABp_nbUfI0ajLIOyZSA2bku_JZfo73gYy_W1wFGoZthBykCbWl1sPe3xmiYaAnboEALw_wcB) and broadcasts information wirelessly to the other Arduinos. The wireless system uses the [[LoRa research|LoRa protocol]] to communicate at 915 Mhz. For detailed information on what LoRa is and how it works, please refer to the [[LoRa research]] page. The diagram for states and communication codes is on [Whimsical](https://whimsical.com/rf-states-and-communication-codes-TEZgio2TPLtG5tm47541Hq). The prior link redirects you to the diagram.

-We are using a Vortex wind sensor. One revolution per second equals 2.5 mph. Since our anemometer has a relay (a mechanical switch), it creates a _switch bounce_. Therefore, we need a debounce circuit.

-_A bug with the current code seems to be related to saving the dateTime string. The dateTime string is saved incorrectly when there should be a trailing 0 in front of the minute reading. I believe that the current code does not include an additional 0 to save minute readings below 10.
+- We are currently supplying power to the Arduinos via USB. If we use efficient Buck converters from the batteries to the Arduinos, we might save some electricity.
