## Getting Started
### Dependencies
[LoRa library](https://github.com/sandeepmistry/arduino-LoRa)
The dependency can be removed by commenting out the `#define USE_LORA` in `fdrs_sensor.h`
### [Sensors](https://github.com/timmbogner/Farm-Data-Relay-System/tree/main/FDRS_Sensor2000)
Sensors gather data and send it to a gateway via ESP-NOW or LoRa.
