Embedded System
In this world of knowledge everything around us is run by Computing Systems. The technical Brilliance and Developments in different fields has led to a drastic change in our lives especially in the communications field. Due to various changes in technologies many systems have come up with breathtaking developments. One amongst them is the Embedded Systems. It is the evolution or further development of computing system. Its applications provide tremendous opportunities for creative use of computer technology. Almost every new system introduced in the market is an example of Embedded System.
An embedded system is a combination of computer circuitry and software that is built into a product for purposes such as control, monitoring and communication without human intervention. Embedded systems are at the core of every modern electronic product, ranging from toys to medical equipment to aircraft control systems.
In contrast to general-purpose computers, embedded systems perform a narrow range of pre-defined tasks. Thus, they usually do not have any of the typical computer peripheral devices such as a keyboard, display monitor, serial connections, mass storage (e.g., hard disk drives), etc. or any kind of user interface software, unless required by the product in which they are used in. This can make it possible to greatly reduce the complexity, size and cost and increase the robustness of embedded systems as compared with general purpose systems.
SECTION V:
In this project we are detecting persons with human heat detection sensor, if this sensor is placed at room doar we can get good result . with this sensor when person coming to room it will give indication to the microcontroller. Here we are interfaced Relays to the microcontroller , with this microcontroller signlas we get on/off the lights with human detection sensor signals .
With above system we can Totally eliminates loss of energy in homes/offices, i.e. it detects human intruder only. It can detect presence of intruder small to large area i.e. it can detect up to
14meters with 110 degree freedom. With the help of microcontroller and Relays we can switch lights and fans through the human detection sensor. with this process we can save lots power save in our offices/homes.
