The disclosed embodiments include methods and systems for providing a notification relating to a geographical boundary based on monitored sensor data collected by networked devices. The disclosed embodiments include, for example, a method for receiving, by one or more processors, a request to establish a first boundary around a first location. The method may also include monitoring, by the one or more processors, one or more triggering devices. The method may also include calculating, by the one or more processors, a first boundary extent delimiting the geographical area of the first boundary based on one or more boundary extent parameters. The method may also include detecting, by the one or more processors, whether at least one of the one or more triggering devices is located within the first boundary extent. The method may also include, when the at least one of the one or more triggering devices is detected within the first boundary extent, sending, by the one or more processors, a notification to a client device based on the determining.
