This thesis goes over the design and development of an emergency button device and an accompanying Android application, that is aimed at helping people message an emergency contact, with their location, in the case that they are lost, hurt or perceive themselves to be in danger.
The emergency button system is comprised of two different devices, the emergency device, containing the emergency button, and an Android smartphone. The emergency button device sends out an alert message through Bluetooth, if the button on the device is pressed, notifying the smartphone of the situation. The smartphone will then take action, getting the GPS location of the user’s phone and send it to an emergency contact through SMS.
During this project a functioning prototype was created for the emergency button device using a BGM121 Bluetooth module and a Blue Gecko Bluetooth development board. A custom Android application was created for smartphones to work with the emergency button device. The groundwork for the next phase in the development was laid out, including the electrical schematic for the succeeding prototype, with an estimated 425-day battery life, and software designs.
