Is it possible to fix forbidden zones with GPS coordinates on the Arduino base and let's say activate the alarm when someone enters this territory?

Question

Arduino

For example, this device is installed on a dog and she cannot run around the football field. Will it be possible to fix the football field based on GPS coordinates and notify the owner if the dog crossed this border.

Answer 1

GPS has fairly floating accuracy. Poor dog :-(
In fact - yes. This task can be solved using arduino and a gps module. But the quality will most likely be so-so
