I am designing a GPS tracker and what i wanted is to detect if GPS tracker is moving or not (i kept GPS tracker in car).
If i am able to find that car is not moving then i can put GPS in standby mode and can save some battery. And once Car start moving then i can awake GPS and keep logging the data.
Looking for IC which i can incorporate in MY PCB to find movement.
I tried with accelerometer but it can not detect linear motion.(till now i didn't find any ways to check linear motion).
Please suggest me any inexpensive solution.
