Aiming at the safety of divers' underwater gas supply, a set of real-time monitoring and verification scheme for wearable divers' gas supply safety is designed based on underwater wireless short-distance transmission technology and MS5837 pressure sensor technology. The test shows that the scheme can efficiently collect key technical indexes such as air supply pressure and residual pressure of gas cylinders carried by divers, and achieve a wireless short-distance transmission effect of about 1.0 meters underwater, which can meet the design requirements of divers' underwater air supply safety monitoring scheme.
