First, the hardware
Connect what you have. Decide what it does.
Brain is a physical industrial cabinet. Your electricians connect the facility. Your team builds the application, operating logic and AI on top of documented interfaces.
Sensors and equipment in one system
Inputs
Climate, water, energy, cameras, doors and existing systems
Brain
Industrial I/O, local compute, firmware, permissions and diagnostics
Outputs
Lights, pumps, valves, HVAC, alarms and approved equipment
Once connected, Brain can become the controller, tracking tool, security workflow or facility application your team creates.
Possibilities, built by you
One machine layer. Many possible applications.
These are examples of what a customer could create. Brain is not a locked cultivation or compliance product.
Plant vision
Use PoE cameras and the included NVIDIA Jetson for your own growth, uniformity or anomaly models.
Plant and batch tracking
Connect identifiers, events and facility data to a tracking application designed by your team.
Compliance workflows
Build jurisdiction-specific records, approvals and system integrations without treating the hardware as a compliance guarantee.
Access and security
Connect approved readers, door contacts, cameras and alarms to customer-defined permissions and event workflows.
Multi-site operations
Repeat the same Brain hardware across rooms and facilities while keeping each application under your control.
BRAIN CULTIVATION PLANNER
Plan your cultivation control system.
Describe your facility, choose what Brain should control and select the level of sensing you need. The configurator separates your Interkey order, supplier purchases and project allowances into one complete cost plan.

THE BRAIN PLATFORM
One local platform for control, sensing, vision and your own AI.
Industrial Brain controller
CompuLab SBC-IOT-iMX8Plus running the Interkey control and data platform locally.
- NXP i.MX8M Plus · ARM64
- 14-inch industrial panel
- Local firmware, storage and automation
- REST, WebSocket and MQTT interfaces
Wired field network
RS-485 / Modbus RTU connects distributed sensors, meters and remote I/O across the site.
- Configurable serial network
- Daisy-chain field topology
- Isolated segments and termination where needed
- Fibre or local cabinets for larger distances
Local NVIDIA Jetson AI
PoE cameras feed local vision models without requiring continuous cloud video upload.
- Up to 20 PoE camera connections per active Brain
- RTSP / ONVIF camera integration
- Crop, growth and anomaly analysis
- Lens, resolution and lighting selected for the scene
Your software, your logic
Use Brain Firmware and the open integration paths to build the automation and AI your operation needs.
- Historian, alarms and audit history
- Modbus TCP, MQTT and OPC UA
- CSV, JSON and PDF exports
- Local operation with optional external services
CONTROL PRINCIPLEWireless and vision sense; your control program decides; wired hardware acts.
Wireless sensors, cameras and AI may adjust approved setpoints and modes inside configured limits. Emergency stops and critical interlocks for irrigation, heating, ventilation, dosing and fertigation remain wired.
The sensor connects to the corresponding Brain input without a protocol gateway.
A conventional industrial signal is wired to a Brain digital input.
Interkey configures the device address, register map and RS-485 network.
The displayed package price includes the interface needed to connect the device.
Interkey selects the exact variant, accessories and installation details for the site.

WHAT THIS BUILD UNLOCKS
The parts are only useful because of what you can build.
Brain supplies the hardware, firmware, safe machine interface and local Jetson. Your team owns the software, cultivation logic and AI.
Room-by-room climate recipes
Control temperature, humidity, CO₂, fresh air, circulation and dehumidification independently for mushroom, flowering or vertical growing rooms.
Measured substrate and nutrient delivery
Combine moisture, pH, EC and flow with your own crop recipe, then control irrigation or dosing separately for every room.
Lighting and HVAC coordination
Schedule lighting groups and environmental loads around crop phases, power limits, energy prices and safe equipment states.
Private room vision
Use low-light PoE cameras and the included Jetson for growth, contamination, uniformity or anomaly models without mandatory cloud video.
Room access and security events
Connect approved door contacts, readers and alarm paths so your application can record access, notify operators and request permitted responses.
ENGINEERING HAND-OFF
Review the plan. Then request your quotation.
Review your configuration before sending. This does not place an order. Interkey checks the regional variants, I/O allocation and availability before preparing a quotation.
Clear by design
Platform, not prescribed software.
Is Brain a finished cannabis management system?
No. Brain is physical industrial hardware and firmware. You build the applications, workflows and interfaces on top.
Could we build plant tracking or compliance workflows?
Those are possible customer-built applications. Regulatory suitability depends on your implementation, integrations and jurisdiction.
Can it connect to access, security and facility equipment?
Brain is designed to connect software with approved cameras, sensors, I/O and equipment under configured permissions and engineering limits.
Where can the platform be deployed?
In professional operations where cultivation and the proposed application are lawful. Every deployment must be checked against local licensing, safety and facility requirements.
For professional use in jurisdictions where cultivation is legal. Applications shown are possible examples, not finished compliance products or legal advice. Connection methods, safety functions and equipment authority are reviewed for the real installation.
