AC Infinity AI CO₂ + Light Sensor – Smart CO₂ Monitoring & Intelligent Day/Night Automation
Take complete control of your indoor growing environment with the AC Infinity AI CO₂ + Light Sensor. Designed exclusively for the AC Infinity Controller AI+, this intelligent environmental sensor continuously monitors carbon dioxide (CO₂) levels and light intensity, providing accurate real-time data that allows your grow room to automatically maintain ideal growing conditions.
By combining precise CO₂ monitoring with light detection, the sensor allows the Controller AI+ to intelligently coordinate fresh air exchange (FAE), CO₂ supplementation and environmental equipment based on whether your grow lights are on or off. The result is a smarter, more efficient growing environment that maximises CO₂ availability during photosynthesis while reducing unnecessary ventilation and wasted CO₂ during dark periods. :contentReference[oaicite:0]{index=0}
Key Features
- Designed exclusively for AC Infinity Controller AI+
- Accurate CO₂ (PPM) monitoring
- Integrated ambient light sensor
- Automatic day and night detection
- Optimised Fresh Air Exchange (FAE) automation
- Intelligent CO₂ enrichment programming
- Real-time environmental monitoring
- Supports AI-powered climate automation
- View historical environmental data through the AC Infinity app
- Simple plug-and-play installation
Smarter CO₂ Management
Carbon dioxide plays a vital role in photosynthesis, but maintaining stable CO₂ levels while balancing ventilation can often be difficult. The AI CO₂ + Light Sensor continuously measures CO₂ concentrations and supplies this information directly to the Controller AI+, allowing it to intelligently manage ventilation equipment and CO₂ supplementation based on real environmental conditions.
Instead of relying on fixed timers or manual adjustments, the Controller AI+ can dynamically respond to changing CO₂ levels, helping create a more stable and efficient growing environment.
Intelligent Day & Night Detection
The integrated light sensor automatically detects whether your grow lights are operating, allowing the Controller AI+ to apply different environmental strategies during light and dark periods.
During lights-on periods, the controller can prioritise maintaining ideal CO₂ levels for active photosynthesis. During lights-off periods, it can adjust ventilation behaviour to avoid unnecessary CO₂ usage while continuing to maintain a healthy growing environment.
Optimised Fresh Air Exchange (FAE)
Fresh Air Exchange is essential for maintaining healthy plants, but excessive extraction can quickly remove valuable CO₂ from the grow space. By combining CO₂ readings with intelligent fan programming, the AI Controller can balance ventilation and CO₂ retention far more effectively than conventional timer-based systems.
This intelligent approach helps improve environmental stability while making more efficient use of supplemented CO₂.
Real-Time Environmental Monitoring
When connected to the Controller AI+, live CO₂ and light data can be viewed through the AC Infinity app, giving growers instant visibility of changing environmental conditions.
The app also stores historical environmental data, allowing growers to analyse trends, review CO₂ performance and fine-tune their growing environment over time. :contentReference[oaicite:1]{index=1}
Expand Your AC Infinity AI Ecosystem
The AI CO₂ + Light Sensor forms part of the expanding AC Infinity AI ecosystem and works alongside compatible controllers and environmental sensors to create a fully connected smart grow room.
For maximum functionality, pair it with:
- AC Infinity Controller AI+
- Compatible AC Infinity UIS™ Grow Lights
- AC Infinity CLOUDLINE Inline Fans
- AC Infinity Humidifiers, Heaters and Environmental Equipment
Together these products create a fully automated growing system capable of intelligently managing temperature, humidity, VPD, airflow, lighting and CO₂ from a single controller.

Frequently Asked Questions
Does this sensor work with Controller 69 PRO?
No. The AI CO₂ + Light Sensor is designed specifically for use with the AC Infinity Controller AI+.
Why does it include a light sensor?
The integrated light sensor allows the Controller AI+ to automatically distinguish between day and night, enabling different CO₂ and ventilation strategies depending on whether your grow lights are operating.
Can it automatically control ventilation?
Yes. When connected to the Controller AI+, the sensor provides real-time CO₂ and light data that can be used to intelligently manage compatible AC Infinity equipment and optimise fresh air exchange.
Do I need Wi-Fi?
No. The sensor operates directly with the Controller AI+, while Wi-Fi connectivity simply enables remote monitoring, historical data and additional smart features through the AC Infinity app.
Smarter Environmental Control Starts Here
The AC Infinity AI CO₂ + Light Sensor gives the Controller AI+ the information it needs to intelligently manage CO₂ enrichment, fresh air exchange and day/night environmental strategies. Whether you're looking to improve plant performance, reduce wasted CO₂ or build a fully automated grow room, this intelligent sensor provides the precision and control needed for the next generation of indoor growing.
