Method and device for detecting falling off of exhaust sensor, air conditioner and storage medium

The invention relates to the technical field of air conditioners, and discloses a method for detecting falling off of an exhaust sensor, which comprises the following steps: acquiring real-time operation parameters of an air conditioner every first preset duration; and determining a current operation parameter and a historical operation parameter according to the real-time operation parameter. Wherein the current operation parameters are real-time operation parameters obtained at the current moment. The historical operation parameters are real-time operation parameters obtained at a preset historical moment. And whether the exhaust sensor falls off or not is determined according to the current operation parameters and the historical operation parameters. In this way, whether the exhaust sensor falls off or not can be checked according to the current moment and the change between the current operation parameters and the historical operation parameters at the historical moment, and therefore the accuracy of det
