The STMicroelectronics Sensor Hub driver is a software component used by various devices, particularly laptops, tablets, and other portable devices, to manage the collection and interpretation of data from built-in sensors. These sensors may include accelerometers, gyroscopes, magnetometers, ambient light sensors, and other types of motion and environmental sensors. The Sensor Hub driver helps the operating system communicate with the hardware and manage sensor data, which can be used for a variety of functions like screen orientation, gesture recognition, fitness tracking, and other applications that rely on environmental or motion data.
