A high populated country like India has to meet the increasing demand for food so irrigation in India should be highly sophisticated in terms of yielding additional food grains. Keeping this mind we implemented a Microcontroller Based Automated Irrigation System. This is an improved food production technology and makes full use of agriculturalresources.
Proper prediction about the requirement of water is facilitated using a micro controller in this automated micro controller based automated irrigation system water is fed to the paddy fields whenever there is an intense need based on the prediction of soil moisture, The value of the pipes is controlled by the micro controller and minimizes the human errors and saves time and human effort.
Operation of the proposed circuit:
Automate irrigation system project works based up on the micro controller and the GSM modem, if the water level in the soil is below the desired level the micro controller sends a message to the farmer by means of GSM modem, if the user gives a missed call to the particular modem number the micro controller get activated and operates the relay and the relays stats the motor after sensing the required water level the micro controller sends triggers the relay circuit and the mission stops.

Specification and Advantages:
This entire process to be performed the microcontroller needs to be programmed so for we program the automated irrigation system micro controller based on the requirements using embedded c programming language.
This system had several advantages, its saves a lot of human and electrical energy, maintains proper water regulation based o the weather conditions and also prevents loss of water, it is less complex and easily controlled even by illiterate persons within minutes of time, the maintenance cost is very low.
Introduction to brain machine interface:
In this paper, we will see how the brain machine interface is made and how the capabilities of the human being can be extended. We will about the advantages of using brain machine interface and the problems faced by this.
The capabilities of a human being are limited and a capability of a machine is higher but it cannot think of its own. Research is going on for making a machine to interface with the brain by which the capabilities of a human being are far extended.
Brief on brain machine interface:
The human brain takes decisions based on the impulses generated in the body and in a human body we find millions of neurons which generate impulses. So a chip is designed and it is placed in the human body and it is made to integrate with the nerve fibers. The chip is interfaced with a remote computer outside.
The chip senses the impulses generated in the body and performs the tasks with the help of the remote computer or the server located outside. The chip is designed by using nano technology and it is constructed in such a way that it can generate the power required for it through heat generated in the body or by the flow of blood circulation.
The chip has successfully placed a body of professor in a university and he could control the appliances without lifting his hand from a given range.
Proposed Brain Systems in Future:
The proposed brain machine interface chip can be very helpful to make the organisms to work properly for the paralyzed patients. By using brain machine interface the human capabilities gets increased a lot and many technological advancements can be made.
But due to this there may differentiation in between the persons who are using the interface chips and the normal human being. All details about this system explained in the given ppt presentation.

Interesting Features in Artificial Intelligence:
The speed of computation and neural networks are some of the features that make a system more intelligent. It also includes filtering and displaying of responses that are meaningful and also provides a solution to a particular question. Plus, the algorithms divide the task into several subtasks called recursion.

Similar like that of humans brain, computers also sometime face the problems of understanding a particular situation and adapting to a new one. The behavior of the machine improved only due to the artificial intelligence. The improved behavior helps in tackling the complex jobs that are based on the deliberate reasoning of high level, abstract thoughts and recognition of patterns. The artificial intelligence can help in understanding the process by recreating it. It helps to enhance it beyond the capabilities of the present situations.
Ambiguity makes it difficult to understand the meaning that is intended for certain sentences and phrases. It also makes difficult to understand the inferences. Symbolic logic is an unambiguous knowledge representation that is developed originally in order to formalize the attempt for reasoning of mathematics.

The limitation of semantic networks is the structure that is added which also makes it necessary for distinguishing. The object properties and relationships of the statement are the twodistinguishedfeatures of the frames. A frame comes with structures in addition and it is simply a node that facilitates the relationships between the object properties and the objects itself. It is known as a representation of slot-and-filler.

Comparing wireless and wifi technology. Wireless technology is a future technology where as WI-FI technology is general purpose network.
Introduction to ZIGBEE:
ZIGBEE is a high level communication protocol, this technology is intended to provide an cheaper and simple means of short range data transfer when compared to other wireless communications such as blue tooth, WPAN,s etc. these systems requires only 10% software requirements of conventional Bluetooth systems and these are cost effective, low power consuming devices, and highly reliable. These systems had self healing mechanisms, and can be accessed to multiple nodes.

Data transfer methods:
In ZIGBEE based wireless communication there are three modes of data transfer they two ways of data transfer between the coordinator and the device, i.e. coordinator to device, device to coordinator, pear to pear data transfer i.e. point to point data transfer. In pear to pear topology each individual device can communicate with its preceding device directly, as already mentioned above this ZIGBEE concept has self forming and a self healing characteristic which makes this system reliable in mesh networking.
