Protection of the child/ elderly/ disabled/ pet by smart and intelligent GSM and GPS based automatic tracking and alert system

This article discusses in detail the purpose, designing and functioning of a tracking system. This tracking system could be brought to use to track pets/children/elderly/disabled/vehicles etc. The tracking system's range can be specified depending on the usage. If the carrier of the tracking system intentionally or unintentionally tries to cross a particular predetermined area/ region then an SMS is sent to a predefined phone number disclosing the coordinates of the location. The working of the system is based on an existing GSM network and GPS satellites. This tracking system not only transmits the longitude and latitude coordinates to the cell phone but also gives a slight shock to the carrier and sets off an alarm indicating the crossing of the periphery.
