This is an original design of a GPS tracker designed on Elab and it is intended to be used as a security device for beehives, but it is not limited to this. It can be used everywhere a motion-activated GPS tracker is needed, like your car, bike, or even your boat.
It is a GPS tracker controlled by simple SMS commands and it is designed for reliability, low power consumption, and ease of use. It features a MEMS accelerometer that is used to intelligently detect movement and once triggered it will power on the GPS module and will try to acquire the current coordinates. The location details will be transmitted to the owner’s smartphone via a simple SMS and then follow update the coordinates at predefined intervals.
- Remote management via simple SMS commands
- High reliability – no need to babysit the tracker due to crashes and resets
- Long battery life – over 1-year standby on a single charge (2500mAh battery)
- 3-axis high sensitivity MEMS Accelerometer
- Intelligent Triggering – it will not be triggered by accidental movement
- Selectable Trigger Sensitivity Level
DESCRIPTION OF OPERATION
The tracker has 3 main modes of operation, detailed below:
In standby mode, the GSM and GPS modules are powered down and the microcontroller is in sleep mode, resulting in a current draw of approximately 70uA, mainly by the accelerometer (MMA7660). The accelerometer is used to detect movement caused by a possible thief.If the accelerometer is triggered 1 or 2 or 3 times (depending on the sensitivity level) inside of a 60-second window then the device will enter tracking mode. While in standby mode the tracker will also enter ready mode approximately every 12 hours, triggered by the microcontroller’s internal RTC. This is to check for incoming commands and battery status etc.
