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 ...

What are Sensors and its type.



SENSORS

Automatic control systems several parameters such as tem nature, light, level, proximity, Limit are to be sensed and conveyed to a control devise for the purpose of output control

The above parameters are generally sensed by different devices

l as sensors. Those sensors give appropriate signals to the rol device. The device picks up the signal from those devices to check the condition of the system on receiving the input. The aut signals given by the sensors are passed to the control device in terms of ON-OFF logic signals

Sensors are detectors that can measure some type of physical quality that is happening, such as pressure or light. The sensor will then be able to convert the measurement into a signal that one will be able to read. Most of the sensors in use today are actually going to be able to communicate with an electronic device that is going to be doing the measuring and recording. Today, you are going to be able to find sensors in a wide range of different devices that you use regularly. The touch screen that you have on your phone has sensors, and they use pressure sensors for opening the doors at the market. Sensors are a very common part of everyday life.


History of Sensors:
Sensors have been around for quite some time in various forms. The first thermostat came to market in 1883, and many consider this the first modern, manmade sensor. Infrared sensors have been around since the late The 1940s, even though they’ve really only entered the popular nomenclature over the past few years. Motion detectors have been in use for several years

 The answer is going to depend upon the exact type of sensor in question. For the electric thermostat, the inventor would be Warren S. Johnson. While it might have seemed crude by the modern standards that we have today, this the thermostat was able to keep temperatures within a degree of accuracy  something better than some of the low-quality thermostats on the market today! The first motion sensor used for an alarm system came about in the early part of the 1950s and was the invention of Samuel Bagno. His device made use of ultrasonic frequencies as well as the Doppler Effect.


What are the Different Types of Sensors?

In today’s world, you will be able to find sensors that can detect several different things. The following are some of the most common sensor types out there and a bit about each of them.  Understanding more about the different types of sensors can help you determine which ones you might need to have for your own applications.

Automatic Plant Water Moisturizing .

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,...

WHAT IS WEB 2.0..??

                          The 2nd stage of development of the Internet, characterized especially by the change from static web pages to dynamic or user-generated content and the growth of social media is known as WEB 2.0.                            Web 1.0, which started the whole damn internet and the  Web 2.0  that we all use and love so much. Web 1.0 was just a set of  static websites. It comprised of a load of websites with no interactive information. But as the internet got faster and faster, the web wasn’t only restricted to viewing content. People started participating. Interactive content started flourishing on the servers worldwide. This is the web we all know and love spending so much time on. This is the age of Facebook, Twitter, Youtube… . What does  Web 1.0  mean?     ...

How to make a Final Year Projects and its important.

why  final year projects  are important for the students to improve their career? Obviously, the academic projects of the students only have the power to show the right path to them for their careers. Usually, there are many domains for the academic projects in both hardware and software fields. Nowadays, there are many innovative domains for the academic projects in both hardware area as well as the software area. In the same way, if you wish to complete inventive projects and you did not have any idea about your project, it is advisable to hand over your project to the best project center. Importance: Usually, when you apply for a job interview in MNC’s and any of the corporate companies, the first thing they prefer in you is your academic project. Hence it is more important for your career. So choose your final year project in your interested area. If you are a good programmer and you are interested in coding, choose the software projects. Likewise, if you are inte...
