摘要：This paper discusses the design and implementation of context-aware sensor tags that can be attached to various containers. The tags are designed to be utilizable in non- standardized fruit boxes, and can identify whether fruit has been loaded in a box because they are attached inside the box. After recognizing normal load status, data are sent only when there is content. The tags were designed and implemented to measure distribution by detecting the movement of the fruit box, and sending data through a context-aware function that determines whether fruit is loaded, and a data-transmission event; the tags also send data periodically, even when the fruit box is not moved
