This application provides an automotive intake pressure sensor, which uses a barrel-shaped chip mounting base with one open end and one closed end. The sensor chip is placed inside the chip mounting base, and the printed circuit board is placed outside the chip mounting base. The chip mounting base seals the gas medium inlet, directing the incoming gas medium directly to the sensor chip at the bottom of the barrel. The printed circuit board is not exposed to the gas medium and will not be contaminated or damaged by the gas medium. When high-speed medium rushes into the barrel-shaped mounting base, it presses the sensor chip firmly against the bottom of the barrel. This effectively seals the pins at the bottom of the barrel with through holes, eliminating the need for additional sealing structures such as sealant. This not only reduces processing steps but also avoids the disadvantages of using adhesives, effectively improving the sensor's service life.
