In this paper we present a new concept on controlling the street lights intensity based on the density of the traffic, our main objective is to save the un-used energy electrical energy in street lights management, we can’t control the intensity of conventional High intensity discharge lamp (HID) using in present situations, so in order to control and regulate the light intensity now a day’s LED’s are replacing these ordinary discharge lamps, implementing pulse width modulation technique  in sensing the densities of the moving vehicles, as the number of vehicles are high then the corresponding intensity of the light in that particular lane is maintained high and vice versa; this dynamic approach in varying the light intensity minimizes the wastage of electrical energy. This entire operation is controlled by micro controller in which the entire scenario is programmed and stored.

Every product we find in our daily life is somehow designed with embedded systems. Embedded system is a co design of software and hardware products that is in that is in the hardware we create some functions using software programming we control the hardware. For effective operation and efficient analysis of Engineering design processes, embedded system is taking an integral part. embedded products are the main concern because of its time reaching perfection and reliability from data analysis to many works.

In this project we interface a high voltage electrical device (DC / AC motor) to a personal computer system which is a high sensitive electronic good. To the controller and personal computerRS232 is the communication medium between them and by sending signals from the integrated personal computer to the controller, we control the dc motor.

To avoid complications, water level in a dam should to be maintained properly. This to be performed manually and operators required full time supervision. Without the exact knowledge of water level that is up to where the water present in the dam or reservoir and its inflow rate, it is impossible to control the gates to a man and it may lead to wastage of water.

The main objective behind this project is to provide a real time flexibility to control the gate movements by developing a system based on mechatronics which detect the water level and thereby controlling the dam gates movement and wastage of water. In this project we connect a set of sensors to a stepper motor through microcontroller and the project works through sensors sense the water level gives instruction to microcontroller.

Final Year Electronics Project Abstract for GSM Based SCADA Project

Introduction to GSM Based SCADA Project:

SCADA (supervisory management and information acquisition) usually refers to industrial management systems (ICS).

The term SCADA typically refers to centrally set systems that monitor associated management entire sites what is more as advanced systems that detached over large areas (anything from a structure to a nation).

ICS are laptop systems that monitor and management industrial infrastructure and facility primarily based processes in ways that describe below:

Industrial processes embrace those of producing, production, power producing, fabrication, and purification, and might run in nonstop, group, repetitive, or separate modes.

Infrastructure processes could also be public or personal, and embrace water handling and distribution, waste matter assortment and management, oil & gas pipelines, electric power broadcast and distribution, wind farms, protection warning systems, and enormous communication systems.

Facility processes occur each publicly facilities and personal ones, as well as structure, airports, and area stations. They observe and management HVAC, contact, and energy utilization.

The term SCADA usually refers to centrally set systems that monitor and management entire sites similarly as advanced systems that detached over massive areas (anything from an plant to a nation).

Most of the system is controlled mechanically by RTU’s and powerful microcontrollers.

This project introduces a complicated system mistreatment GSM technology whereby observation and dominant is completed through SMS’s from a certified itinerant.

SCADA systems usually implement a distributed info, ordinarily cited as a tag info, which contains information parts known as tags or points.

Some extent represents one input or output price monitored or controlled by the system.

Points are often either “hard” or “soft”. A tough purpose represents AN actual input or output at intervals the system, whereas a soft purpose results from logic and math’s operations applied to alternative points. 

We will style a RTU comprising a microcontroller interfaced with a Temperature device for temperature and a digital display for display.

ADC0804 is connected to a MICROCONTROLLER. This project principally deals with superior management and information acquisition of temperature management parameters like heat and cold to manage the temperature.

Different Multipliers Using VHDL Embedded Systems Abstract

Introduction to Different Multipliers Using VHDL Embedded Systems Project:

The power consumption concern and the little occupancy are the major requirements of the fabrication of the DSP systems and other efficient performing systems. The important criteria for improvement are the enhancing speed and space of the multiplier. The speed and the space are relied on each other which mean increasing speed concludes with the more consuming space. 

We have focused to come out with a conclusion by studying more multipliers. We have studied three different multipliers differently. We found that the serial multipliers needs more power consumption compared to parallel multipliers. The project has three different multipliers called Booth Multiplier, Wallace Tree Multiplier and the Vedic Multiplier. 

The conclusion assists to select the proper multiplier for the fabrication of the systems. The multipliers are the part of the systems with presence at many places. With the analysis of the multipliers, we are able to construct a system with less power requirement and space. 

The Project  suggests for the Vedic Multiplier which is based on the Vedic multiplication method or called Sutras. The method is commonly and conventionally applied to calculate the multiplication of the two or more numbers in the decimal system. The Project also focused on the same method for the binary number system to form the algorithm which can run on digital hardware. The Vedic multiplication method used here is Urdhava Tiryabhyam for calculation of the binary system.
