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 part per billion levels. This is critical in enclosed space settings. Successful ethylene monitoring will enable efficient crop management. PNet-Mon will be compatible with size, power and sensitivity requirements of NASA for long-term human spaceflight missions. In addition to NASA application during human spaceflight missions, PNet-Mon will prove to be a valuable tool in any greenhouse, food processing, storage and distribution facilities. The benefits of integrating PNet-Mon into any produce/crop supply chain would be of great interest to the industry in terms of product quality and marketability, and production cost. By monitoring ethylene gas, the optimal harvest time and/or storage time/conditions can be determined. Thus, producers can achieve optimal fruit quality and ripeness. PNet-Mon supply chain integration can help prevent produce spoilage caused by deleterious levels of ethylene gas. By preventing spoilage, companies could save time and money associated with spoiled produce.
