[0002] Moisture is an important index of grain quality and a key factor affecting the safety of grain storage. If the moisture in grain storage is too high, it is easy to cause problems such as heating and mildew. During the storage process of granaries, through the on-line monitoring cloud platform for moisture, people can conduct real-time monitoring of the moisture of granaries on terminals such as mobile phones and computers.

[0003] At present, when people conduct on-line detection of the moisture of granaries, a moisture detector located inside the granary is used for detection operations. However, the position of the moisture detector is often fixed, and it can only specifically detect the moisture of the grain in a certain area, unable to meet the need for moisture detection of grain in multiple areas. To solve this problem, people generally install multiple moisture detection instruments inside the granary for operation. At this time, there are too many detection devices inside the granary, and the operation is rather troublesome. Therefore, it is urgent to design an on-line automatic detection and transmission device for the moisture of granaries to solve the above problems. Summary of the Utility Model
