Device and measurement system for the geomechanical characterization of a soil, as well as the corresponding measurement method This measuring device (200), which is practical and efficient, comprises a housing (210), to be secured to a dynamic penetrometer (100), an electric power supply battery (250), housed in the housing, and an electronic system. (240) which is housed in the housing and connected to the battery. The electronic system comprises an accelerometer, as well as a distance sensor, which, in use, is oriented towards a ground and which is adapted to determine the distance between the measuring device and the surface of the ground by measuring the time required for a wave to make a round trip between the distance sensor and the ground surface. The electronic system also includes a control unit which, when the battery powers the entire electronic system, is adapted to apply processing to measurement signals from the accelerometer and the distance sensor.
