The invention discloses a solar wireless geomagnetic sensor which is characterized by comprising a sensor kernel and batteries and further a support. The center of the support is provided with a sensor kernel mounting hole; the middle part of the support at the periphery of the sensor kernel mounting hole is provided with more than two battery mounting holes; the battery mounting holes have the same disposition direction as the sensor kernel mounting hole and are annually distributed by taking the center of the sensor kernel mounting hole as the center; the sensor kernel and the batteries are respectively arranged in corresponding holes disposed on the support; the sensor kernel is electrically connected with the batteries; and preferentially, the solar wireless geomagnetic sensor also comprises a battery cover, wherein the opening end of the battery cover is connected with one end of the support, and the other end of the support and the batteries are sealed in the battery cover. The solar wireless geomagnetic sensor is mainly used for the detection of vehicles driving on the highway, solves the problem that the prior wireless geomagnetic sensor adopts the single battery without an external power supply to supply power to lead to the frequent change of the battery and has the advantages of small maintenance workload and long service life.
