Pressure sensor is a device that can accurately measure and sense the pressure of a gas or liquid, which converts the physical quantity of pressure into an electrical signal that can be processed and transmitted. In the automotive, industrial, medical and many other fields, pressure sensors play an indispensable role. Especially in the automotive sector, pressure sensors are widely used in key parts such as engine management, brake systems, tire pressure monitoring and air conditioning systems to ensure the safe, comfortable and efficient operation of the vehicle. These sensors monitor and feedback pressure changes in real time, helping vehicle systems achieve precise control and timely adjustments to ensure the safety of drivers and passengers.
