Abstract:An embedded system is a combination of hardware and software along with necessary interfaces and connections to electromechanical components, sensors and actuators etc., for performing the desired function.
Sensors provide the interface between external environment and the embedded system. While maintaining the environment, sensors read input signals/data/. Data if analog is digitalized to make it usable for digital processing unit. This data is then processed and outputted in some specific format user(s) and may also generate and transmit commands for actuators for specific functionality.In our paper we also implemented the model of an automatic door opening system. All the requirement phase components are discussed in our paper which can be implemented and applied further through programming.

INTRODUCTION
Embedded systems interact with the physical world to perform a single application or a small set of tasks e.g. control, protection and monitoring of processes, machinery, environment, and equipments. It is a combination of hardware and software along with necessary interfaces and connections to electromechanical components, sensors and actuators etc., for performing the desired function. Although an embedded system has some component, it is not itself a general-purpose computer. These systems are embedded usually in a larger system for some specific purpose other than to provide general purpose computing.
