The sensor industry contributes a strong force in national defense construction, and the core technology of high-tech national defense development is sensor technology. The sensors equipped in modern ships include pressure sensors, temperature sensors, torque sensors, etc. There are over 150 temperature sensors and over 150 pressure sensors used in every 10000 ton class ship. The larger the tonnage, the more sensors are used. In addition, to understand the impact of natural environment on system performance, it is necessary to equip various sensors such as temperature and humidity sensors to monitor natural environmental parameters. Various sensors such as pressure sensors, differential pressure sensors, temperature sensors, humidity sensors, and other related information sensors have also been applied on space shuttles. With the increasing maturity of sensors in the military, it has become possible for weapons and equipment to “see”, “communicate”, “think”, and listen to “command”. Sensors give silent objects intelligence and will provide important support for integrated joint combat command and decision-making systems. Sensors help to create a real “trap” in the future war environment. China will be firm in confidence, face difficulties, turn crises into opportunities, and create a Xintiandi.
