Microchip — Location-Tagged SOS, Asset Tracking or Vehicle Tracking Reference Design

Microchip Location-Tagged SOS, Asset Tracking or Vehicle Tracking Reference Design

Featuring the host SAM D21 MCU

This Microchip location-tagged SOS, asset tracking or vehicle tracking application demo shows a solution based on the SAM D21 32-bit microcontroller (MCU) which is easily expandable and can be reused for multiple applications to send a distress signal via a location-tagged SOS SMS text message.

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
