The embodiment of the invention provides an intelligent atomizer and a control method, which relate to the technical field of atomizers. The intelligent atomizer comprises an atomizer body, an information acquisition module, an information analysis module and a fog amount control module. The information acquisition module is arranged on a shell of the atomizer body. The information analysis module and the fog amount control module are arranged in the atomizer body. The information analysis module is electrically connected with the information acquisition module and the fog amount control module. The information acquisition module is used for acquiring current environment information of a point to be measured and transmitting the current environment information to the information analysis module. The information analysis module is used for outputting an electric signal to the fog amount control module when the current environment information meets a preset condition. The fog amount control module is used for controlling a first nozzle in multiple nozzles on the atomizer body to rotate to a preset position based on the electric signal, so that water fog is sprayed out from the first nozzle. The appropriate nozzle is controlled according to the detected current environment information so as to spray to the current environment, so that the water resource is saved.
