Magnetic force transmission type tire pressure sensor device and related setting tool and setting method

A magnetic force transmission type tire pressure sensor device (10) and related setting tool (20) and setting method is disclosed. The invention uses a magnetic force sensor unit (19) in the tire pressure sensor device (10) to receive lines of magnetic flux being transmitted by a magnetic force transmitter unit (25) in the setting tool (20), and then the received waveform is converted into a communication protocol and stored in the tire pressure sensor device (10). Therefore, the invention not only can achieve the purpose of wireless transmission but also can enhance the stability of signal transmission, eliminate wireless regulatory constraints and improve product quality.
