The value of Canada’s annual grain crop is about $6 billion and 70% of the produced grains are exported. It is estimated that 2% of the harvested crop (worth $120 million) gets wasted during handling and storage. Most buyers specify stringent quality requirements as well as zero-tolerance for contaminants. The current method of grading grain relies heavily on manual inspection, which is time consuming, subjective and requires trained personnel. Therefore, alternative rapid, objective, accurate, and cost effective techniques are needed for grain quality monitoring in real-time that can potentially assist or replace manual inspection. The quality of grain also deteriorates during storage, which could be anywhere from a few months to over a year in Canada. With the disappearance of country elevators over the last few decades, more grain is being stored on-farm for longer periods. This has led to larger-sized bins that are difficult to monitor. Hanging temperature and moisture sensors on cables in these large bins poses many practical limitations. Thus, a non-invasive method of monitoring quality of grain stored in bins is highly desirable.

加拿大每年的粮食作物价值约为60亿美元，70%的粮食用于出口。据估计，2%的收获作物（价值1.2亿美元）在处理和储存过程中被浪费。大多数买家指定严格的质量要求以及对污染物的零容忍。目前的粮食分级方法严重依赖人工检查，这是耗时的，主观的，需要训练有素的人员。因此，需要替代的快速、客观、准确和成本有效的技术来实时监测谷物质量，这可能有助于或取代人工检测。谷物的质量在储存过程中也会恶化，在加拿大，储存时间从几个月到一年多不等。在过去的几十年里，随着乡村升降机的消失，更多的粮食被储存在农场里更长的时间。这导致了难以监测的较大尺寸的垃圾箱。将温度和湿度传感器悬挂在这些大型垃圾箱的电缆上会带来许多实际限制。因此，非常需要一种监测储存在仓中的谷物的质量的非侵入性方法。
