We are building a tracking device that sets off an alarm when the user is a certain distance away from the transmitter. Mbed code utilizing 2 KL25Z microcontrollers, 2 XBees (1 transmitter and 1 receiver), Adafruit Ultimate GPS Breakout v3, and two BLE HC-05 Low Energy Bluetooths.
The device will prevent people from losing their valuable items. When the receiver is at a certain distance away from the transmitter, a buzzer will go off alerting the person that they have left something behind. The transmitter will consist of one XBee, a BLE HC-05 Low Energy and a KL25Z microcontroller.
The receiver will consist of one XBee, a KL25z microcontroller, an Adafruit Ultimate GPS Breakout v3, and BLE HC-05 Low Energy. We need the receiver XBee to take the GPS current location data and send it to the transmitter XBee and convert it to a physical address.
