The invention discloses an exhaled air detection method, an exhaled air detection device is adopted for detection, the exhaled air detection device comprises an electric control board and an air flow path, the air flow path comprises an air inlet connector, a drying filter, an air pump and a detection box which are connected in sequence, and an air sensor is arranged in the detection box; the method comprises the steps that the air pump is started to drive airflow flowing in through the air inlet connector to enter the detection box after being treated by the drying filter, and the gas sensor in the detection box conducts sampling detection on gas components accumulated in the detection box. A gas sensor is installed in an independent detection box, a gas detection cavity is formed in the detection box to meet the requirement that exhaled gas exists in the gas detection cavity and is accurately detected by the gas sensor, and in the detection process, an air pump is matched to drive the ...
