A tire pressure monitoring system with an intermediate bluetooth interface has at least one character detector, an intermediate transceiver and a portable apparatus. The character detector is securely formed inside a tire of a vehicle, detects a tire pressure or an interior temperature inside the tire and sends out a low power consumption electromagnetic wave signal. The intermediate transceiver receives the low power consumption electromagnetic wave signals, transforms the low power consumption electromagnetic wave signals to bluetooth signals and sends out the bluetooth signals. The portable apparatus has a monitor, is portable and receives the bluetooth signals to display information corresponding to the tire pressure or the interior temperature of the tire on the monitor to a person.
