Geofencing
Geofencing is a term that refers to defining a geographic area using a virtual boundary. It’s a feature you can use on electronic devices such as smartphones. A geofence is created when a virtual area is defined within a real-world location. For example, you can set up invisible boundaries around your smartphone. This often involves a combination of hardware (such as a GPS chip) and software in the form of operating systems.
Applications geofencing
Geofencing has a wide range of applications. The best-known example of this technology is its use with smart home devices such as thermostats, lights, robot vacuums, and security systems. For example, a system can be triggered the moment the last person in a family leaves a preset area. In that case, the alarm will be activated, the thermostat will be lowered, the lights will turn off, and all non-essential devices will be shut down. When one of the family members returns home, the opposite trigger will be activated. The devices will then automatically turn back on. With this form of geofencing, a home will respond to presence.
