Project background
Large grow rooms suffer from microclimates — corners that run hotter, humid pockets near irrigation, and stale zones at canopy height. The client wanted a distributed control system that could respond to local conditions, not just room averages.
Challenge
Deploying enough sensors to capture spatial variation without drowning the controller in data. Fusing readings into a coherent climate map, and driving fans, vents, and dehumidifiers in zones rather than as one monolithic system.
Approach & solution
We built a wireless mesh of low-power sensor nodes feeding an edge controller that maintains a live climate heatmap. Actuators were grouped into zones, each with its own setpoint and priority. The system anticipates cross-zone impacts before acting to avoid chasing oscillations.
Results & benefits
Microclimate hotspots were eliminated across the pilot facility, and crop uniformity improved visibly batch-over-batch. Operators now see the room as a map rather than a single number.
