The present invention provides a method for calibrating sensitivity of a sensor node which can automatically calibrate sensitivity of a geomagnetic sensor of a specific sensor node or a specific geomagnetic sensor. According to the present invention, the method for calibrating sensitivity of a sensor node for detecting a vehicle comprises: a step of receiving detection information of a vehicle from a sensor node including a geomagnetic sensor; a step of calculating a calibration value to calibrate the sensor node based on the detection information of the vehicle; and a step of transmitting the calculated calibration value to the sensor node. The sensor node adjusts the geomagnetic sensor based on the calibration value to detect a vehicle.
