PNet-Mon is intended for use in plant growth systems and chambers in space. Once integrated into NASA systems, PNet-Mon will provide vital quantitative information, in situ, about the ethylene gas levels. The rugged, compact, and portable sensor will detect ethylene at parts per billion levels. This is critical in enclosed space settings. Successful ethylene monitoring will enable efficient crop management and prevent spoilage. PNet-Mon will be compatible with size, power and sensitivity requirements of NASA for long-term human spaceflight missions.In addition to supporting human spaceflight missions, PNet-Mon will prove to be a valuable tool for any greenhouse, food processing, storage and distribution facility. The benefits of integrating PNet-Mon into any produce/crop supply chain would be of great interest to the industry as it could improve product quality and marketability generating lower production costs. By monitoring ethylene gas, the optimal harvest time and/or storage time/conditions can be determined. Thus, producers can achieve optimal quality and ripeness. PNet-Mon supply chain integration can help prevent produce spoilage caused by undesired levels of ethylene gas.
