In order to enable users to have a more accurate and comprehensive understanding of the gas composition inside the oxygen chamber,a safe and comfortable indoor environment has been created.Multiple types of sensors are used to collect information on the gas composition inside the oxygen chamber,reducing the impact of the high-pressure environment on the sensors.Bluetooth wireless technology is used to transmit data,mobile phones or tablets display data,and cloud service platforms manage data,forming a monitoring system that includes data collection,display,alarm,and wireless remote transmission functions.Through on-site testing,this design can stably and reliably provide data on the gas inside the oxygen chamber and the operating status of equipment for personnel inside and outside the cabin.It is a new type of design with simple operation and strong practicality.
