Grower Tip
- Plan the Controller AI+ sensor ports before setup; it accepts two sensors and the standard UIS four-port splitter is not suitable.
- Use day and night scheduling so CO₂ programming follows the active light cycle.
- Treat the light reading as lux only; this sensor does not measure PAR or DLI.
Features
Measures CO₂ from 0–40,000ppm and light from 1–65,535lx for environmental tracking.
Controller AI+ integration adds app data, alerts, scheduling and adaptive automation.
CO₂ and fan programs can respond to measured concentration for coordinated fresh-air exchange.
The 3.6m sensor lead supports flexible placement between the grow space and controller.
Fast light response and combined sensing allow day and night programs to follow the detected light cycle.

Test automation
Configure supported fan or outlet equipment through Controller AI+ and test each automation before leaving it unattended.
Which controller works with the CO₂ and light sensor?
The sensor is designed specifically for AC Infinity Controller AI+. Connecting it to that controller enables app readings, data tracking, alerts, day and night scheduling, precision cycling and supported equipment automation. Other Controller 69 models are not listed as compatible with this sensor.
What ranges does the sensor measure?
It measures CO₂ from 0 to 40,000ppm and light from 1 to 65,535lx. The listed response times are 60 seconds for CO₂ and 120 milliseconds for light, with a 3.6m connecting lead. Its listed operating range is 0–50°C and 35–60% relative humidity.
Does the light sensor measure PAR or DLI?
No. The light channel measures illuminance in lux and helps the controller distinguish light and dark periods. It does not measure photosynthetically active radiation or calculate daily light integral, so it does not replace a PAR meter.
How many sensors can Controller AI+ accept?
Controller AI+ has two sensor ports. Plan both connections before combining this unit with another sensor. The standard UIS one-to-four splitter is not designed for sensor expansion, so it should not be used for that purpose.
Can the sensor control fresh-air exchange?
When paired with Controller AI+ and supported equipment, CO₂ and fan programming can alternate in response to measured concentration. This enables fresh-air exchange and minimum intake-speed programs to be coordinated around a selected PPM target.
Description
The innovative CO2 + Light sensor is designed for direct use with our cutting-edge AI controllers featuring adaptive self-learning to automate a crucial role in monitoring and maintaining optimal CO2 levels essential for healthy plant growth.
The precision of the sensor ensures exact control and dispersal of carbon dioxide within grow spaces. When connected to our Wi-Fi app, view accurate, real-time data, ensuring plants receive the ideal amount of CO2 for maximum growth.
Smart Response to CO2
Smart programming allows the sensor to coordinate with a fan to detect the most acceptable amount of CO2, turning the fan on only when needed generating the most efficient fresh air exchange (FAE) and points per million (PPM). This directly impacts the efficiency of photosynthesis, leading to healthier and more robust plants.
Compatibility
Enhanced features including day and night scheduling, precision cycling, and comprehensive environmental data tracking significantly optimize the sensor's performance and overall benefits. These capabilities allow for precise control and monitoring, ensuring the sensor operates efficiently under varying conditions.
KEY FEATURES
- This sensor is designed for use with the AC Infinity AI Controllers to help monitor CO2 levels through adaptive automated learning.
- CO2 sensor pairs with AI Controllers and our Wi-Fi enabled app to precisely control and disperse carbon dioxide within grow spaces based on most beneficial light cycle.
- Custom CO2 and fan programming dynamically alternate to activate in response to carbon dioxide levels optimizing FAE (Fresh Air Exchange)
- Additional programming includes day & night scheduling, precision cycling, and environmental data tracking.
- Smart programming can set minimum intake speed to improve efficiency of plant environment based on PPM.
- NOTE The LIGHT sensor does not measure DLI or PAR
The AI Controller only has 2 sensor ports, and currently can not take more than 2 sensors - AC Infinity is working on a splitter that will accept more sensors (the current UIS 1-4 splitter does not work for sensors)
