Embedded Technology predominates as it overcomes the drawbacks of all the existing mechanical and electronic systems. An embedded system is housed on a single microcontroller board with the programs stored in ROM.

Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense.

GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS.

The project is intended for tracing whether a human is alive or dead in a hazardous zone or mines over a particular area.

A temperature sensor is fitted with the human body as a tag.

The sensor will sense the body temperature and feed it

to the comparator circuit. The circuit will compare the temperature with reference value, and if it finds the temperature to be abnormal it triggers to GSM module and transmits signal which defines the human is alive.

The robot if picks this signals it stops there and triggers the alarm. The project uses the Atmel series of microcontroller
