I’ve been googling a lot, so I really hope someone here can give me a push.
This kind of GPS Shield looks pretty interesting: GPS datalogging shield for Arduino
The plan is I have several vehicles, moving around a 2-3 miles range. I want to find out where they are on Google Map (or at least knowing how far they are away from the end point).
I don’t want to spend money on mobile data plan, and wifi is not feasible at all. So I am down to radio transmission.
Getting one of these GPS modules, at least 2 of them comes with antennae (GPS datalogging shield for Arduino), are they capable of transmitting data back to my office?
Now the real question is: how do I capture the GPS data from each GPS module (each car) at any time? What equipments do I need? I am capable of writing some kind of server to handle the incoming data.
Battery. I can’t use AA battery. Is there a cheap way to hook up the power to the car’s power?
Can someone please list the basic hardware requiremnts? So far I need arduino, GPS module (with anteena support), and what else? What exactly is a receiver and transmitter? Which one is going to sit in my office?
Any recommended pre-built module?
Radio transmission. In particular, plain radio, or cellular? Different drivers have different phones. No way I can find a shield and an adapter that matches every one. I might have some misunderstanding here. Please correct me.
