In this video, We will learn how to make a cool geofencing project uisng sim 800L, GPS module and Arduino. This project constantly checks if the object is within the fence and when the object go outside the fence it immediately send an alert message to your mobile phone. This project can be used on objects that you don't want to go after a given distance.

What is Geofencing:
Geofence is a virtual geographic boundary, or a fence, defined by GPS technology. It enables software to trigger an alert, when and object enters, or leaves a particular area. It can be used to monitor livestock and other animals. parents can used it, for child monitoring.


In this project, I am using circular geofence technique. This technique works on the initial position (starting point) and maximum distance (radius). The resulting geofence is look like a circular shape. The project continuously calculate the current distance from the initial position of the object. and then it checks if the current distance is exceeded from the maximum distance. and if that's the case, then the project will send an alert message to your mobile phone.

For calculating the current distance of the object from the initial position, I have used the Haversine formula: This is a well-known formula that is used to calculate the distance between two GPS coordinates. After calculating the current distance I am comparing it with the maximum distance. If the current distance exceeded the maximum distance. then first, I have started the buzzer for 1 second. and then send an sms alert to your mobile phone, using send alert function.
