Geofencing
Geofencing is a term that refers to delineating a geographical area using a virtual boundary. This is an option used in several advanced devices. A geofence occurs when a virtual area is formed within a location that exists in the real world. For example, you set invisible boundaries around your smartphone in this process. This often involves a combination of hardware (such as a GPS chip) and software in the form of operating systems.
Applications geofencing
Geofencing is very broadly applicable. The best-known example of the application of this location-based technology is the optimal use of smart home amenities such as the thermostat, lamps, robot vacuum cleaner and security devices. For example, it is among the possibilities that the system will be triggered the moment the last person in a family leaves the preset virtual area. In that case, the alarm will activate, the thermostat temperature will be lowered, the lights will turn off and all unnecessary appliances will be turned off. The moment one of the family members comes home, the opposite trigger will kick in. The appliances will then automatically turn on again. Thus, in this form of geofencing, a home will respond to presence.
