System and method for atmospheric gridding monitoring by using gas sensor array

The invention relates to a system for atmospheric gridding monitoring by using a gas sensor array. The system comprises gas sensing units and a cloud server. The number of the gas sensing units corresponds to the number of air monitoring stations arranged in a monitoring area in a gridding mode, and the gas sensing units can send at least one collected monitoring signal which can reflect a pollution degree of a target gas to the cloud server; and the cloud server can convert the monitoring signal sent by the gas sensing units in the monitoring area into monitoring data. Each gas sensing unit comprises at least two sensors integrated on the same substrate so that the gas sensing unit can detect the target gas in an array manner, and defects of poor gas selectivity and cross response of a traditional metal oxide sensor are overcome. 本发明涉及一种利用气体传感器阵列进行大气网格化监测系统，包括：气体传感单元和云端服务器。气体传感单元的数量与监控区域内的以网格化布置的空气监测站的数量相互对应，并能够向云端服务器发送其采集的至少一种能够反应目标气体污染程度的监测信号；云端服务器能够将监控区域内的气体传感单元发送的监测信号转换成监测数据。气体传感单元包括至少两种集成于同一基底的传感器，以使得气体
