Technical Field

[0001] The utility model relates to the technical field of tire pressure detection sensors, in particular to an external tire pressure detection sensor. Background Art

[0002] As an important component of a car, the main consideration for tire performance is tire pressure. Too low or too high tire pressure will affect the tire's performance and reduce its service life, ultimately affecting driving safety. Tire pressure monitoring uses an external tire pressure detection sensor to detect tire pressure.
