Adam Vadala-Roth has posted on Hackaday.io about a connected control system for all agriculture applications based on RS485 control nodes and multiple wireless sensor networks:
Agricoltura is the culmination of multiple projects I’ve worked on in the past related to the sensing and control of agriculture systems, notably HydroPWNics and SunLeaf. Agricoltura aims to unite all the concepts of those past projects into a new system based primarily on RS485 nodes for control of pumps, sensor sampling, and light control.
The base system will be a gateway controller linked to daisy chainable RS485 nodes designed for specific functions. These nodes are built around a board called Vine.
Vine allows interfacing of QWIIC connect sensros and devices as well as relay control. Coming in as two varients Vine can be used to setup and control complete hydroponic farming systems or any other agriculture system.
