Method for providing service of tracking location using smart sensor

摘要

Disclosed is a method for providing a location tracking service using a smart sensor. A relay device includes a gyro sensor, an acceleration sensor, and a terrestrial magnetism sensor. Sensor values and RSSI signals measured by the gyro sensor, the acceleration sensor, and the terrestrial magnetism sensor are received from a beacon using a low power Bluetooth (BLE). A device of providing a location tracking service calculates a separation distance between the beacon and the relay device from the RSSI signals, and calculates the movement distance and movement direction of the beacon from the sensor values. So, the separation of objects or children from a protection area can be prevented.
