PREMISE A CO 2 control system is important for investigating how elevated CO 2 affects plant growth. Our automatic CO 2 monitoring and control system offers an inexpensive and flexible way to make CO 2 ‐enriched environments. METHOD AND RESULTS Using microcontrollers paired with non‐dispersive infrared CO 2 sensors, relays, and valves, we developed a low‐cost system for monitoring and controlling CO 2 levels in growth chambers. CONCLUSIONS Compared with existing commercially available CO 2 control systems, Arduino‐based microcontrollers offer affordable access to the data logging of CO 2 levels in growth chambers, thereby reducing budget limitations for creating growth conditions with highly controlled CO 2 concentrations.
