Mushroom growers need stable climate control. With the Moduline Mini I, they gain simple tools to manage every parameter and improve the full growth process.

Industrial mushroom growing is a balancing act. Humidity, CO₂, temperature, airflow, and lighting shape each stage of the growth cycle. When these factors drift, mushrooms change shape, texture, and even taste. Because of this, growers often chase the perfect recipe yet struggle with complex control systems.

The GOcontroll Moduline Mini I offers a clear and flexible path forward. It brings modular I/O, fast processing, and visual programming through MATLAB/Simulink and Node-RED. As a result, growers can build a complete climate controller and keep it easy to use. Even better, the controller supports data monitoring, which allows a digital twin to develop beside the physical crop.

The Moduline Mini I is a compact modular controller with up to four I/O modules, high-brightness RGB LEDs, and several communication interfaces.

It fits mushroom environments well because:

Modular hardware adapts to each farm

Mushroom rooms differ in size and equipment. Therefore, the controller must scale. With module options such as input modules, output modules, and 4–20 mA modules, the Mini I can read:

• Humidity sensors

• CO₂ transmitters

• Temperature probes

• Airflow sensors

• Lighting control signals

And it can drive:

• Fans

• Heaters

• Humidifiers

• Air valves

• LED lighting

Because modules drop into dedicated slots, growers can adjust the controller as production expands or as recipes evolve.

Strong processing for real-time control

The Mini I uses an NXP i.MX 8M Mini application processor. It runs compiled MATLAB/Simulink models and manages multiple loops at once.
This helps control:

• Temperature ramps

• Humidity cycles

• Fresh-air exchanges

• CO₂ thresholds

• Day–night lighting patterns

Simulink makes these tasks visual, which keeps complexity low.

Built for industrial environments

The enclosure is CNC-milled aluminum with IP-rated sealing.
It tolerates vibration, moisture risk, and wide temperatures from −20 to 85 °C.
This is ideal for farms, where rooms can be humid, cold, or frequently washed down.

Node-RED comes preinstalled on the Mini I.
It lets growers adjust key climate parameters without touching the core control logic.

Clear separation of roles

• Engineers create the main control model in Simulink.

• Operators tune setpoints and schedules using simple dashboards.

Because of this separation, changes become safe and predictable. Meanwhile, the system stays flexible.

What operators can change

Using GOcontroll’s Simulink read/write nodes, the dashboard can expose:

• Humidity setpoints

• CO₂ thresholds

• Fresh-air percentages

• Temperature targets

• Lighting duration

• Fan duty cycles

• Stage-based control curves

These values update live. As a result, growers can tune each growth phase without downtime.

Visual monitoring

Node-RED also supports live charts and trend history. This helps operators react quickly when a room drifts outside its window. It also makes training new staff easier, since the interface explains itself.

Mushroom growth passes through predictable phases. Each phase wants slightly different conditions. Because Simulink is visual, growers can express these strategies using blocks instead of low-level code.

Typical Simulink structure

A model may include:

• PID blocks for temperature and airflow

• State machines that step from incubation to pinning to fruiting

• Routines for humidifier pulsing and intake-fan cycling

• Safety logic based on K15 voltage and supply voltage signals

After compiling the model, the software is uploaded to the controller through the GOcontroll upload server.
Boot time for Simulink execution is about 5.5 to 6 seconds.
This allows quick restarts during development.

Precise control enables consistent harvests

Mushrooms respond strongly to climate shifts. Therefore, maintaining stable curves helps shape:

• Cap size

• Stem length

• Texture and firmness

• Moisture content

• Flavor expression

With steady control loops, growers gain predictable outcomes. This keeps batches uniform from one harvest to the next.

A digital twin is a virtual copy of the growing room. It mirrors the chamber by using the same variables: humidity, temperature, CO₂, airflow, and light cycles. When these values feed into the model, the twin shows how mushrooms should grow under ideal conditions.

Why a digital twin helps

It allows the grower to:

• Compare the expected curve to the real sensor data

• Detect drift early

• Test new recipes safely

• Predict growth rates

• Explore taste and texture changes linked to climate shifts

Because Node-RED and Simulink already expose all sensor data, creating a digital twin is a natural next step. The twin evolves as the model improves, and the model improves as new data arrives. As a result, growers tighten control of the full biological process.

Improving the control strategy

When the digital twin and real data differ, this difference highlights where the control logic may need tuning. Therefore, engineers can refine airflow curves, change lighting transitions, or adjust humidity bands. Over time, the twin becomes more accurate, and production becomes more stable.

The Moduline Mini I gives growers a clear toolkit: modular hardware, a strong processor, and easy-to-use software. With Simulink, they design the brain of the climate system. With Node-RED, they operate it in a friendly way. And with digital-twin insights, they improve every growth cycle.

Because all parts work together, the system adapts to different rooms, recipes, and mushroom strains. In short, it helps growers reach consistent quality while exploring new flavors and textures at the same time.
