[Vinnie] developed an RS-485-based irrigation system for his farm, using a Raspberry Pi and custom valve master boards to control distant sprinklers reliably. This solution scales efficiently by conserving power through smart 12V line management and allows each valve node to report status independently.
This innovation is crucial for developers looking to automate large-scale agricultural systems with reliable long-distance communication and efficient power usage, setting a precedent for future IoT projects in agriculture.
