How to do Geofencing on Arduino?

Using Arduino Project Guidance
1

I am new to Arduino so pardon if the question is stupid.

I have tried asking around. The answers I got were confusing since they were full of abbreviations I did not understand.

How do I do geofencing on Arduino? Once the device exits the virtual premises, I want an SMS to be sent to the owner's device and be notified.

Is it possible? If yes, what electric components should I have?

You will need a GPS receiver, be out of doors with a clear view of the sky, and an Arduino running some code that reads the GPS receiver, then compares the current coordinates with the coordinates of the boundary.

It is not hard to find tutorials on the web. Example: Getting Started with the GeoFence - SparkFun Learn

That depends on your expectations. Hollywood films present a rather unrealistic picture. Geofencing using GPS devices provide an accuracy of about +/- 5m if you have a clear view of the complete sky in the whole area.
So geofencing an Australian farm is feasible while geofencing a 200m2 garden won't work.
