I wounder if you know there is a direction sensor? I need it in my project there need to know if an object is going up or down direction. None of my contacts know where I can get it. Thanks in advance!
axis sensors usually calculate the acceleration and
can be used for direction calculation .
It is used on submarines when underwater navigation has to be done and GPS signal is not present .
GPS if I am not wrong does also provide direction information .
Motorola and philips have acceleration sensors. I heard that they are restricted items and cannot be exported outside the USA. Maybe they can be used in guidance systems or something.
