Background
Our country is a big country of agricultural population, but per capita arable land area is very low, so very high requirements are put forward for improving the arable land quality and the agricultural product yield. With the progress of agricultural technology, people gradually realize that the traditional fertilizer is abandoned, and only the industrial fertilizer can produce short-term benefits and easily cause permanent damage to soil. The demand for traditional fertilizers in agricultural production has therefore increased year by year.
On the other hand, with the rapid development of social economy and the higher level of urbanization in China, a huge amount of garbage is generated every day in cities with more and more concentrated population. Waterworks also produce large amounts of sludge during water treatment. In addition, the vigorous development of the breeding industry also produces large quantities of livestock manure every day. Also, agricultural production produces a large amount of crop straw each year. If the waste is treated in a traditional way, on one hand, the waste is greatly wasted, and on the other hand, the environment is also greatly polluted. The aerobic composting technology solves the problem of environmental pollution caused by the traditional garbage and straw landfill or burning mode on one hand, improves the soil quality on the other hand and improves the crop yield by a mode of fermenting garbage wastes to generate high-quality organic fertilizers in a high-temperature aerobic environment. The aerobic composting technology is low in cost and easy to operate, so that the aerobic composting technology is gradually widely applied.
In aerobic composting techniques, in addition to temperature and humidity, the oxygen content inside the heap plays a decisive role in the quality and duration of the compost. Due to the particularity of the stacking medium and the environment, the method puts high requirements on the automatic and accurate detection of the oxygen content of the stack. The traditional sampling measurement mode and the traditional respiration rate test mode are gradually eliminated due to poor accuracy, timeliness and operability. Currently, the more common real-time detection methods include: the oxygen content of the surrounding environment of the stack body is detected, the oxygen content in the stack body cannot be measured in the mode, and the error is large; in addition, the other method is to pump out gas by an air pump for detection by arranging a long gas path pipeline (Chinese patent: a device for continuously and automatically measuring the oxygen content in the loose solid medium, patent No. CN 1397796A; a monitoring device for monitoring the oxygen concentration in the compost and a monitoring method thereof, patent No. CN 106680432A).

An effective solution to the problems in the related art has not been proposed yet.
