How it works

Each subsystem (temperature vent/heater, humidity fogger, CO2 injector) is a simple closed-loop controller: sensors read the current state, compare it to a setpoint, and drive an actuator proportional to the error.

error = setpoint − measured
actuator = Kp · error  (proportional control)
growth = f(temp,hum,CO2) → product of Gaussians
        centered on each optimum

Temp / humidity / CO2 setpoints — targets the automated system tries to hold; the plant's growth index peaks when all three are near their biological optimum.
Heatwave disturbance — an external shock added to the greenhouse temperature that the controller must reject.
Auto Control toggle — turns the feedback loop on/off so you can see actuators freeze and conditions drift when disabled.

Real application: commercial autonomous greenhouses use exactly this sensor-actuator feedback to cut water/energy use while maximizing yield per square meter.
