A sensor platform being installed on a vehicle traveling on a road or a sports training device, the sensor platform including, a sensor unit configured by an acceleration sensor for capturing environmental data transmitted from an object to be surveyed, a data selector/variable filter for selecting necessary data or limiting data frequency of the environmental data transmitted from the sensor unit, a sound sensor for capturing sound signals from the object to be surveyed, and a processing unit for running computer programs including algorithms for controlling the sensor unit and the data selector/variable filter, processing output data from the data selector/variable filter and the sound sensor, and setting a threshold level, wherein the processing unit processes the output data from data selector/variable filter when the sound signal level is more than the threshold level.
