AC Infinity AI+ Environmental Controller with CO₂ & Light Sensor

AC Infinity Controller AI+ with CO₂ and Light Sensor

The AC Infinity Controller AI+ with CO₂ and Light Sensor combines intelligent grow-room automation with real-time carbon dioxide and light monitoring. This complete bundle is designed for growers who want deeper insight into their environment and more precise control over lighting, ventilation, temperature, humidity, VPD and fresh-air exchange.

Eight built-in UIS ports allow compatible grow lights, extraction fans, circulation fans, humidifiers, heaters and other equipment to operate through one intelligent control hub. With suitable UIS splitter hubs, the system can be expanded to manage up to 32 compatible devices.

The included CO₂ and light sensor adds real-time PPM and light-level data, allowing the AI+ to coordinate compatible ventilation equipment according to carbon dioxide levels and day or night conditions. In other words, it gives your grow room another pair of eyes—although thankfully, these ones do not judge your pruning.

What Is Included?

• AC Infinity Controller AI+ – eight-port intelligent UIS environmental controller
• Corded climate sensor – monitors temperature and relative humidity inside the grow space
• Built-in climate sensor – provides a second temperature and humidity monitoring zone
• AI CO₂ and light sensor – tracks carbon dioxide concentration and surrounding light levels
• Power adaptor – powers the controller independently of connected UIS equipment

AI-Powered Environmental Control

The Controller AI+ studies how your growing environment responds when connected equipment changes speed or output. It uses previous results to improve future adjustments, helping to reduce temperature, humidity and VPD overshooting.

Rather than repeatedly switching equipment fully on and off, compatible devices can run at a more appropriate output level. For example, an extraction fan can change speed according to current conditions, while compatible lighting can follow programmed schedules and intensity settings.

• Adaptive AI automation – learns how connected equipment affects the grow-room environment
• Eight independently controlled UIS ports – manage multiple compatible devices from one hub
• Expandable to 32 devices – add compatible equipment using UIS splitter hubs
• Dynamic output adjustment – varies compatible fan speeds, lighting intensity and equipment levels
• Temperature, humidity and VPD control – helps maintain a more stable growing environment
• Real-time CO₂ monitoring – tracks carbon dioxide concentrations from 0 to 40,000ppm
• Light-level detection – recognises day and night conditions for more useful CO₂ programming
• Fresh-air exchange optimisation – coordinates compatible ventilation equipment according to CO₂ levels
• Beginner and advanced modes – choose guided automation or detailed custom control
• WiFi and Bluetooth connectivity – monitor and control the system through the AC Infinity app
• Offline programme retention – saved automation continues if WiFi is temporarily unavailable

Monitor CO₂ Levels and Fresh-Air Exchange

Carbon dioxide is essential for photosynthesis, but concentrations can change considerably inside enclosed grow spaces. The included sensor tracks CO₂ levels in parts per million, giving growers real-time information instead of relying on guesswork.

The Controller AI+ can use this information to coordinate compatible ventilation fans and optimise fresh-air exchange (FAE). Fan speeds can be adjusted according to CO₂ concentration, including the use of minimum intake settings where appropriate.

This can help prevent ventilation from running harder than necessary while still exchanging stale air when conditions require it.

Please note: The sensor measures CO₂ and assists with compatible equipment automation. It does not generate or dispense carbon dioxide. A separate CO₂ cylinder, regulator and suitable control equipment are required if active CO₂ supplementation is intended.

Light Detection for Day and Night Programming

The sensor also monitors surrounding light levels. This allows the system to identify day and night conditions and apply different CO₂ or ventilation programmes according to the lighting cycle.

Because plants primarily use carbon dioxide during photosynthesis, coordinating environmental programming with the active lighting period can help growers avoid unnecessary operation during darkness.

Light detection also supports day and night schedules, precision cycling and environmental data tracking through the AC Infinity app.

Dual-Zone Climate Monitoring

The AI+ includes a built-in temperature and humidity sensor plus a separate 3.6m corded climate probe. This allows conditions to be compared across two locations, such as inside and outside a grow tent or at different canopy positions.

Temperature and humidity readings are also used to calculate vapour pressure deficit (VPD), helping growers understand and manage conditions associated with plant transpiration.

Control and Monitor Your Grow Through the App

Connect the Controller AI+ to the AC Infinity app using WiFi or Bluetooth to access environmental data, equipment controls and intelligent automation features.

App features include:

• Real-time CO₂ readings in PPM
• Real-time light-level data
• Temperature, humidity and VPD monitoring
• Remote control of compatible UIS devices
• AI-generated environmental insights
• Day and night programming
• Custom triggers, schedules, timers and cycles
• Minimum and maximum device-output levels
• Environmental alerts and notifications
• Historical climate and CO₂ charts
• Grow guides, recipes and AI assistant support

Saved programmes are stored by the controller, allowing essential automation to continue if the internet or WiFi connection is temporarily interrupted.

Compatible with the AC Infinity UIS Ecosystem

The Controller AI+ can manage a wide range of compatible equipment, including:

• CLOUDLINE inline extraction fans
• CLOUDRAY circulation fans
• IONFRAME and IONBOARD LED grow lights
• CLOUDFORGE humidifiers
• Compatible AC Infinity heaters and climate equipment
• UIS Control Plugs for selected outlet-powered appliances
• Selected third-party grow lights using suitable UIS adaptors

Some older AC Infinity products and third-party equipment require separately available UIS adaptors. Always check compatibility before connecting additional devices.

Frequently Asked Questions

What is the difference between this bundle and the standard Controller AI+?
This bundle includes the AC-COS3 CO₂ and light sensor. The standard AI+ monitors temperature, humidity and VPD but does not include CO₂ or light-level monitoring.

Does the sensor release carbon dioxide?
No. It only measures CO₂ and light levels. Active supplementation requires a separate CO₂ supply, regulator and appropriate control equipment.

Can the controller use CO₂ readings to adjust ventilation?
Yes. Compatible ventilation equipment can be programmed to respond to CO₂ levels, helping coordinate fresh-air exchange and minimum intake speeds.

Can it distinguish between day and night?
Yes. The light sensor detects surrounding illumination and supports different day and night programmes.

How many devices can the controller manage?
It has eight built-in UIS ports and can manage up to 32 compatible devices using suitable UIS splitter hubs.

Will automation continue without WiFi?
Yes. Saved programmes continue running if WiFi is interrupted, although remote app access will be unavailable until the connection returns.

Can it control equipment from other manufacturers?
Selected third-party grow lights and outlet-powered devices can be integrated using the correct UIS adaptor or control plug, sold separately.
