<p>A spatial motion sensor comprises an MCU, and an acceleration sensor, a gyro sensor, a piezoelectric sensor, an electronic compass, a GPS-based positioning module, a wireless communication module, a power management module, a data memory, and a mini-USB interface that are connected to the MCU. The spatial motion sensor uses the acceleration sensor, the gyro sensor, and the piezoelectric sensor to obtain linear acceleration data, angular velocity data, and a piezoelectric pulse signal, and through the wireless communication module, uploads the collected data to a server after the MCU performs simple processing on the data, thereby meeting measurement requirements on various motion states where the direction and the angle change constantly. The spatial motion sensor mainly performs motion state detection, data collection, data processing, data storage, and data transmission.</p> |
