Abstract
A tire pressure detecting apparatus has a micro-controller, a detecting module and a transceiver. The detecting module is electronically connected to the micro-controller and has a tire pressure detecting unit controlled by the micro-controller to detect a tire pressure inside a tire. The transceiver is electronically connected to the micro-controller, transmits a high frequency signal corresponding to detected characteristic tire parameters from the detecting module to a monitoring system inside a car and receives an external high frequency signal sent from external tire pressure detecting apparatus for the micro-controller, with the micro-controller temporarily delaying sending of the high frequency signal until a waiting time has expired to prevent signal collision between the high frequency signal and the external high frequency signal.
