For example, in the research of agricultural greenhouse gas emissions, a large number of gas samples need to be collected within a certain period of time. At present, they are generally collected manually. However, due to the need to calculate emissions with accurate time intervals as weights in the process of gas sample collection, manual sampling generally has problems such as large sampling errors, low efficiency, and cumbersome processes.
