The progression of the human existence from the primitive state to the present technological complex state is just an outcome of observation of this environment. By observing the environment and controlling the various physical parameters like temperature, pressure of the environment the authors are able to sustain on this beautiful earth. In order to control physical parameters there is a need of a specific system called Data Acquisition System (DAS). Man has developed many different data acquisition systems like microprocessor based, PLC based, from rock world to the rocket world. This paper describes the implementation of data acquisition systems using embedded processors.
