The invention relates to the technical field of sensors, in particular to a tire pressure sensor which comprises an inflating valve assembly, a fixing screw, a shell and a sensing assembly, the inflating valve assembly is connected with the shell through the fixing screw, and the sensing assembly is located in the shell. By arranging two antennas, different transmitting frequency bands can be compatible, so that the maximum transmitting signal strength can be kept in the different frequency bands, and the sensor can stably transmit in the different frequency bands and is high in anti-interference capability.
本发明涉及传感器技术领域,尤其涉及一种胎压传感器,包括包括气门嘴组件、固定螺丝、壳体和传感组件,其中,气门嘴组件与壳体通过固定螺丝连接,传感组件位于壳体内部。通过设置两根天线,可以兼容不用的发射频段,使得不同的频段都能保持最大的发射信号强度,进而使得传感器在不同的频段传输都能稳定而且抗干扰能力强。
