The embedded systems are computers which are part of special-purpose devices. Due to the limited duties these systems can be highly optimized to the particular needs. Traditionally most of these systems are used for control and the process measurements to the side effects of higher integration of the circuits more complex applications can be solved by embedded systems. To solve these problems embedded systems are commonly equipped with various kinds of peripherals. Here using the RF technology we can easily protect child kidnapping cases and using buzzer system we can easily alert the parents, if child in the out of range converge.
