Location-Tagged SOS, Asset Tracking or Vehicle Tracking

GPS tracking devices can be used for a variety of applications, from personal tracking of teen drivers, children, the elderly, or individuals with special needs to business tracking for fleet and asset management.

This application demo shows a solution based on a 32-bit microcontroller (MCU) that can be used during an emergency to send a distress signal via a location-tagged SOS SMS text message. Here is a quick overview of how it works:

  • The host SAM D21 MCU communicates with the GPS module over the UART interface to perform the acquisition and tracking of GPS coordinates.
  • The MCU registers event callbacks for location tracking of the GPS receiver
  • The Mikroelektronika GSM-GPS click used in this application contains a hardware module that combines both GSM/GPRS and GPS functionality used to track the device and to send out the emergency or distress signal
  • The GSM/GPRS module is configured to send the location-tagged SOS SMS text message to a specified mobile phone number when the emergency switch is pressed and the GPS position is available
  • A cell phone number can be configured to send a SMS text message when the switch on the board is pressed for more than four seconds
