Problems solved by technology

However, today’s humidity detection instruments are more complicated to detect the humidity of food. It is necessary to accumulate a large amount of food and then detect it as a whole. When the food is less and difficult to accumulate, it is difficult for existing products to quickly detect the humidity.
Some products that can detect the humidity of a small amount of food have slow sensitivity and response speed, which leads to low detection efficiency

Description

technical field [0001] The invention belongs to the field of humidity detection instruments, in particular to a granular food humidity detection system based on a wet detection steady-state circuit. Background technique [0002] There are certain conditions for the storage of beans, grains and other foods, especially not in an environment with high humidity. If the humidity of the food is too high, it is easy to breed bacteria or even go moldy. However, today’s humidity detection instruments are more complicated to detect the humidity of food. It is necessary to accumulate a large amount of food and then detect it as a whole. When the food is less and difficult to accumulate, it is difficult for existing products to quickly detect the humidity. . The sensitivity and response speed of some products that can detect the humidity of a small amount of food are also slow, which leads to low detection efficiency. Contents of the invention [0003] The purpose of the present inv...
