/challenges-projects/design-challenges/on-the-line/b/projects/posts/green-brain---distributed-greenhouse-control-platformTL;DR A distributed CAN bus sensor network for a greenhouse, built around Arduino Nano nodes, an Arduino UNO Q hub, and a Python Flask dashboard. Two of the three nodes reliably report temperature and humidity. One has a wiring fault.
