Abstract

Abstract : PREMISE: A CO2 control system is important for investigating how elevated CO2 affects plant growth. Our automatic CO2 monitoring and control system offers an inexpensive and flexible way to make CO2 ‐enriched environments. METHOD AND RESULTS: Using microcontrollers paired with non‐dispersive infrared CO2 sensors, relays, and valves, we developed a low‐cost system for monitoring and controlling CO2 levels in growth chambers. CONCLUSIONS: Compared with existing commercially available CO2 control systems, Arduino‐based microcontrollers offer affordable access to the data logging of CO2 levels in growth chambers, thereby reducing budget limitations for creating growth conditions with highly controlled CO2 concentrations.
