Abstract
The present invention provides a wireless tire pressure and tire temperature detecting system, using a wireless monitoring and transmission device with a centrifugal switch. When the tire rotational speed of the car reaches a certain speed, it turns on the centrifugal switch. The centrifugal switch is used to turn on the entire wireless monitoring and transmission device to detect, process signal, and transmit. The wireless monitoring and transmission device is not working, until the tire rotational speed of the car reaches a certain speed before it is initiated and causes power consumption. The present invention saves more power consumption than the conventional structure, which extends the shelf life of the wireless tire pressure and temperature detecting system as well as time involved to change the battery, which is practical and convenient.
