The invention discloses an external air inflatable tyre pressure sensor. The external air inflatable tyre pressure sensor comprises a sensor hardware base, a tyre pressure monitoring assembly, a sensor shell, a special valve core, a valve core cap and a solar panel for providing electric energy to the tyre pressure monitoring assembly of the sensor, wherein a sealed frame body is formed by surrounding of the sensor hardware base and the sensor shell; the tyre pressure monitoring assembly is arranged in the sealed frame body; the special valve core penetrates through the tyre pressure monitoring assembly; one end of the special valve core is in butt joint with a lower end cavity of the tyre pressure monitoring assembly and the other end of the special valve core stretches out of the sensor shell to be in thread connection with the valve core cap; and the solar panel is arranged around the outer side of the valve core cap in an annular shape and is fixed on the upper surface of the sensor shell. By virtue of the external air inflatable tyre pressure sensor, the problems that the sensor needs to be detached when a common sensor is inflated, a sealing silica gel ring is abraded by a valve nozzle in a mounting process, and air is leaked when the sealing silica gel ring is not mounted in place are solved. Meanwhile, the solar panel is arranged on the sensor shell so that energy sources are saved and a lithium battery can be charged; and the problem that a button battery is difficult to detach when the button battery of the common sensor is replaced is solved.
