Cheap Component for Travel Detection?

Recommended Posts

For you hobbyists out there, maybe you can enlighten me.  Even though we have GPS, is there a cheaper component which senses an item's movement?  It doesn't have to track where it is going; it just needs to detect that it is traveling.  Direction doesn't matter.

Tile...

 

People have been using it to track people without their knowledge... like women in nightclubs.

Unfortunately, I can't give you a direct answer on your question, but I can recommend to look through these Navigation apps and websites. I like traveling, so I read much about it. Recently I've found a great source, and it has many travel-related categories, including navigation. I'm not tech savvy, but I hope you will find the solution there.

There's any number of IMUs (Intertial Measurement Units) available that can do this. They have gotten very inexpensive for the cell phone market. They're not extremely accurate, but depending upon the model they will give you acceleration, velocity, and/or position, and angle or angular velocity in rotation matrix, Euler, or quaternion.

yes... there are devices to detect movement.

Having a senior moment... trying to remember the term for them.

 

not what I was thinking/groping for...

but these drones have 3 gyroscopes, for stabilization,on a board the size of a matchbook. And room for 4 speed controllers, and a receiver... can't see where a transmitter would be that tough.

 

I'll remember the term. Might take a couple days, tho

thnx @Edgar

accelerometers[sp?] is the term..

A 6DOF (degree of freedom) IMU contains accelerometers in 3 axes and gyros in 3 axes. A 9DOF IMU adds 3 axes of magnetometer. Many of the off-the-shelf IMUs also perform the arithmetic to turn accelerations into velocities and positions, and to turn angular velocities into angles.

There are accelerometers made for shipping high value items that report location, sorry I do not have a model at hand...

i was going to say my ex-wife; but, she wasn’t cheap.
