Farm Data Relay System #####
[***In loving memory of Gay Holman, an extraordinary woman.***](https://www.facebook.com/CFECI/posts/2967989419953119) ##### -The Farm Data Relay System is an easy way to collect data from remote sensors without relying on WiFi. It is based around the ESP-NOW protocol, which is readily available on ESP32 and ESP8266 microcontroller boards. The system can be used to collect and transmit sensor data in situations where it would be too difficult or energy-consuming to provide full WiFi coverage. +The Farm Data Relay System is an easy way to communicate with remote devices without relying on WiFi or LoRaWAN. It is designed to use the ESP-NOW and LoRa protocols to establish lines of low-power, low-cost gateways and repeaters that provide coverage to remote devices. The system can be used to exchange sensor readings or control messages in situations where it would be too difficult or energy-consuming to provide full WiFi/LoRaWAN coverage. FDRS devices are divided into two types. Gateways comprise the infrastructure of the network, moving data in pre-determined directions to provide coverage to all devices. User nodes allow the user to exchange data with the gateways. Each gateway is identified with an 8-bit physical hex address (MAC), while nodes use 16-bit integers to identify datapoints as they move through the system.
