Bluetooth-Armband

The Bluetooth Tracking Bracelet is a device that can locate itself indoors and outdoors using BLE and a motion sensor. It can measure skin temperature, heart rate, blood pressure, and steps.

The bracelet can detect if it is worn by the user. If not, it will enter a low-power mode. It also has an SOS button that can send an alarm message, start locating itself, and report health data. The bracelet can alert the user when it has low power or is shutting down.
