TIRE PRESSURE SENSOR

摘要

A tire pressure sensor is installed on a tire rim which includes an assembly through hole. The tire pressure sensor includes a sensor body, a gas intake nozzle fixed on the tire rim and connected to the sensor body, and a gas nozzle assembly member to couple with the sensor body and the gas intake nozzle. The sensor body includes a gas nozzle assembly hole to couple with the gas intake nozzle, a tire pressure sensing module disposed in the sensor body for detecting a tire pressure, and an update connection port electrically connected to the tire pressure sensing module. Through the update connection port, the tire pressure sensing module receives an update firmware data for updating firmware stored therein in response to different applications.
