POWER STORAGE DETAILS

POWER STORAGE DETAILS Block diagram: The voltage generated by the source (generator) is not of pure dc. This has to be rectified before storage. A diode rectifier then provides a full-wave rectified voltage that is initially filtered by a simple capacitor filter to produce a dc voltage. Block diagram (Power supply) Working principle: The Full Wave Bridge Rectifier Full Wave Bridge Rectifier uses four individual rectifying diodes connected in a closed-loop "bridge" configuration to produce the desired output. The main advantage of this a bridge circuit is that it does not require a special center-tapped transformer, thereby reducing its size and cost. The single secondary winding is connected to one side of the diode bridge network and the load to the other side as shown below. The Diode Bridge Rectifier The four diodes labeled D1 to D4 are arranged in “series pairs” with only two diodes conducting current during each

Automatic Plant Water Moisturizing System For Garden




SYNOPSIS:

            Automatic moisture control in the garden is a multipurpose project, which can be used for both agriculture and domestic purposes. This project is the modification of the automatic plant water system. This is different from another model, but our project an all one project. The touch sensor is used to sense the moisture contents in the garden. Then automatically the pump is On/Off in the garden.





NEEDS FOR AUTOMATION:
             This an era of automation where it is broadly defined as the replacement of manual effort by electric power in all degrees of automation. The operation remains an essential part of the system although with changing demands on physical input as the degree of mechanization is increased. 
Degree of automation are of two types, viz.
·      Full automation
·      Semi automation
In semi automation a combination of manual effort and machine power is required whereas in full automation human participation is very negligible. Nowadays almost all the process is being atomized to deliver the products at a faster rate. The manual operation is being atomized for the following reasons.
·      To achieve mass production
·      To reduce manpower
·      To increase the efficiency of the machine
·      To reduce the workload
·      To reduce the production cost
·      To reduce the time consumptions Quick response 
·      To reduce the fatigue of workers
·      To achieve good quality
·      Less maintenance
Introduction:
            An automatic moisture control system is used in the garden in hotels. It can also be used in the agriculture fields. It consists of a moisture sensing circuit and light-sensing circuit and a regulated power supply circuit.
           The function of the moisture sensor is to sense the presence of required moisture for plants and if there is not enough moisture present if indicates and also switches on the motor. When excess of water is flown if switches on the heater and the switches of the motor.
            The function of the light sensor a circuit is a switch on the tube light when the sun sets and provides the required light to the plant. The function of the regulated power supply is to convert the AC and DC and to give required 12 V for the moisture sensor and light sensor circuit to operate.

Applications:
            The applications of the ‘Automatic Moisture Control’ are as follows.
1.   It is used to maintain costly plants.
2.   It is used gardens in hostels.
3.   It can be used in agriculture fields also.
4.  Since the moisture sensing can be varied it can be used to trees and to maintain plantation fields.
5.   It can be Agriculture colleges for testing costly and new varieties of gardening plants.
6.  It can be used for maintain experimental plants.


Advantages:
           The main advantages of ‘Automatic moisture control system for Garden’ are as follows
1.  Used to maintain expensively plants.
2.  This does not need the attention of people.
3.  Experimental plant are maintained in this method.
4.  Extreme substances like excessive heat and excreting water are eliminated.
5.  Since sensitive of light and moisture can be controlled. This unit can be modified for trees as well.

About Motors and its types...

An electric motor is a motor that uses electrical energy to produce mechanical energy, usually through the interaction of magnetic fields and current-carrying conductors. The reverse process, producing electrical energy from mechanical energy is accomplished by a generator or dynamo. Traction motors used on vehicles often perform both tasks. Electric motors can be run as generators and vice versa, although this is not always arctic Electric motors are ubiquitous, being found in applications as diverse as industrial fons blowers and pumps, machine tools, household appliances, power tools, and disk drives They may be powered by direct current (for example a battery powered portable device or motor vehicle) or by alternating current from a central electrical distribution grid. The smallest motors may be found in an electric wristwatch. Medium-size motors of Highly standardized dimensions and characteristics provide convenient mechanical power for industri

Sugar Glider( Sugar Bear) Information

In the wilds of its native habitat, the Sugar Glider Sugar Bear is a tree-dwelling creature, often living in groups of ten to fifteen. It is active at night when it hunts for small vertebrae and insects. It feeds on the sweet sap of certain species of eucalyptus, acacia and gum trees. The Sugar Glider Sugar Bear is named for its preference for sweet foods and its ability to glide through the air like a flying squirrel. It lives in groups of up to seven adults, plus the current season's young, all sharing a nest and defending their territory, an example of helping at the nest. Adult males mark the territory with saliva and with a scent produced by glands on the forehead and chest, and also mark members of the group with this scent. Visitors who lack the appropriate scent marking are expelled swiftly, even violently. The dominant male mates more frequently with the female of the group than the other males. When an adult member of the group dies, it is normally replaced by

What is a well balanced meal?

A well-balanced meal should contain all the macro-nutrients required for optimum health and to maintain the cells, tissues, and functions of the body.   These nutrients include protein, carbohydrate and a regulated amount of healthy unsaturated fat. Ideally, a well-balanced meal should It also includes a variety of vitamins and minerals. The importance of eating a well-balanced meal It is important to eat well balanced meals most of the time to ensure that your overall diet is also balanced, and that you are getting all the vitamins and minerals required for a healthy body.  Eating healthy, balanced meals will also provide you with plenty of long-lasting energy and keep you full for longer. Obviously, it is not always possible to eat a completely nutritionally balanced plate of food at every meal, but if you aim for a balanced the majority of the time, you will end up with a nutritionally complete diet overall. Try to ensure that each meal contains at least a  prote
