Piezoresistive principle: Atmospheric pressure sensors usually use the principle of piezoresistive sensors. The basic principle is to utilize the piezoresistive properties of induction materials. When subjected to external pressure, the resistance value of the induction material will change, and pressure information can be obtained by measuring the change in resistance value.

　　High precision measurement: Atmospheric pressure sensors have the characteristic of high precision and can accurately measure changes in atmospheric pressure in real time. This is very important for fields such as meteorological forecasting, aerospace, and climate research.

　　Wide working range: Atmospheric pressure sensors can adapt to different working environments and pressure ranges. Whether in high-altitude mountainous areas or deep underground, atmospheric pressure can be stably and reliably measured.

　　Fast response speed: Atmospheric pressure sensors have fast response speed, which can monitor changes in atmospheric pressure in real time and provide important data support for meteorological, climate research, and weather warning.
