Sensor for simultaneously monitoring pressure of nasal cavity and oral cavity

The invention provides a sensor for simultaneously monitoring nasal cavity and oral cavity pressure, which is characterized in that two breather pipes are respectively communicated with the nose and the mouth of a target object, and the two breather pipes are respectively used for guiding respiratory airflow from the nose and the mouth to corresponding air bags; an air pressure sensing module and a tension sensing module are respectively arranged inside and outside the air bag and are used for detecting an air pressure signal inside the air bag and a surface tension signal in expansion and contraction processes; determining a corresponding effective airbag from the two airbags based on the respective surface tension signals of the two airbags; obtaining nose breathing frequency information and mouth breathing frequency information of the target object based on the respective air pressure signals of the two air bags; the nose breathing frequency and the mouth breathing frequency of the target object are detect
