Dimlux CO2 Sensor for Maxi Controller EVO

Accurate CO2 Readings, Dosed Only When It Counts

The Dimlux CO2 Sensor is the link between a Maxi Controller EVO and a CO2 bottle or generator. It uses a dual-beam nondispersive infrared (NDIR) element to measure carbon dioxide in an enclosed grow space and replenish it to a pre-set ppm, holding plants at the level they can actually use. It is powered directly from the wall socket and powers a separate Dimlux CO2 Regulator, releasing gas only as demand requires. A built-in light cell shuts dosing down during the dark period, so nothing is wasted when photosynthesis has stopped.

Key Benefits

• Dual-beam NDIR sensing for accurate, stable CO2 readings
• Precise dosing to your set ppm at all times
• Built-in light cell for automatic shutdown during lights-off
• Powers a separate CO2 regulator as one system
• Simple calibration using fresh outside air
• Ideal for closed-loop rooms and a natural fit alongside OptiClimate

Dosing CO2 Without Knowing Your ppm

CO2 is one of the biggest levers on yield in a sealed room, with growers reporting up to 20% extra weight once levels are properly maintained, but only if the room is holding the concentration you think it is. Dosing blind wastes gas when the room is saturated and starves plants when leakage pulls levels down, and neither shows up until growth quietly slows. A dual-beam NDIR sensor closes that loop.

How to Use

• Mount at canopy height, away from fans and the CO2 outlet
• Connect it to the Maxi Controller EVO and power it from a wall socket
• Calibrate with fresh outside air before first use, then periodically
• Set your target ppm on the controller and let the regulator dose to match
• Leave the light cell unobstructed so dosing halts at lights-off
• Keep the room sealed and temperature under control before enriching
