...Part I INTRODUCTION 1.1 Theories/Concept of the Design Class Volume Monitoring System with Automatic Influx Adjustment is a reliable circuit that takes over the task of counting the number of individuals inside a room very accurately. When somebody enters the room, the counter is incremented by one. When somebody exits the room, the counter will count down by one. The total number of individuals inside the room is displayed on the two 7-segments. Individual Counting is simply a measurement of the individual traffic entering and exiting offices, malls, sports, venues, rooms etc. Counting the number of individuals helps to maximize the efficiency and effectiveness of employees, floor area of an organization, and even the monitoring of the people inside. Individual counting is not limited to the entry or exit point of an establishment but has a wide range of applications that provide information to management on the volume and flow of people throughout a location. A common method for counting the visitors involves sharing human auditors to manually tally the number of individuals who pass by a certain location. But human-based data collection comes at great expense. Our project aims to automate the counting of individuals with the use of a detector called Light-Dependent Resistor which makes it more reliable and efficient. The use of human auditors is redirected to other functions which makes a more productive system. Another feature of this project is...

...CHAPTER ONE 1.0 INTRODUCTION Current trends in electric energy generation are moving towards the utilization of the environment friendly sources of energy, represented by the wind and solar energy ones as a supplementary energy resource. The solar based one is the more attractive because it is characterized by being free, incur no fuel cost, abundant, limits less, distributed all over the world, pollution free, and require little maintenance. Maximizing power output from a solar system is desirable to increase efficiency and in order to maximize power output from the solar panels, one need to keep the panels aligned with the sun. As such, a means of tracking the sun is required. Efficient collection of maximum solar irradiance (MSI) on a flat plate type photovoltaic solar panels or a cylindrical parabolic solar reflector requires adjustments of two parameters of the energy collecting surface namely the angle of Azimuth, and the angle of tilt, of the surface to be illuminated. As the elevation angle of the sun remains almost invariant in a month and varies little (latitude + 100) in a year, there is no need for automatic adjustment of the tilt angle. Everyday, the sun rises in the east, moves across the sky and sets in the west. If one could get a solar panel to turn and look at the sun all day hours, then it could receive the maximum amount of sunlight possible and convert it into the more useful energy (electricity). The current of the solar module is very sensitive...

...gaining the focus as an important means of expanding renewable energy uses. Solar cells those convert sun's energy into electrical energy are costly and inefficient. Different mechanisms are applied to increase the efficiency of the solar cell to reduce the cost. Solar tracking system is the most appropriate technology to enhance the efficiency of the solar cells by tracking the sun. A microcontroller based design methodology of an automatic solar tracker is presented in this paper. Light dependent resistors are used as the sensors of the solar tracker. The designed tracker has precise control mechanism which will provide three ways of controlling system. A small prototype of solar tracking system is also constructed to implement the design methodology presented here. Index Terms:- MPPT I. INTRODUCTION Now a day’s electricity generation using solar mobile has been growing fast day today. In order to obtain solar energy as much as possible, the study of the efficiency for PV systems has attracted many researchers and engineers attention. In general, there are three methods to increase the efficiency of PV systems. The first method is to increase the generation efficiency of solar cells; the second one is related to the energy conversion system include maximum power point tracking (MPPT) control algorithms; and the third approach is to adopt solar tracking system to obtain maximum solar energy input from the sun. In our project we are using the second method, i.e., MPPT...

...CHAPTER-1 INTRODUCTION 1.1 INTRODUCTION TO SOLAR ENERGY Fig. 1.1(a) Block Diagram of Photovoltaic System Renewable energy is rapidly gaining importance as an energy resource as fossil fuel prices fluctuate. At the educational level, it is therefore critical for engineering and technology students to have an understanding and appreciation of the technologies associated with renewable energy. One of the most popular renewable energy sources is solar energy. Many researches were conducted to develop some methods to increase the efficiency of Photo Voltaic systems (solar panels). One such method is to employ a solar panel tracking system. This project deals with a microcontroller based solar panel is always able to maintain a perpendicular profile to the sun’s rays. Development of solar panel tracking systems has been ongoing for several years now. As the sun moves across the sky during the day, it is advantageous to have the solar panels track the location of the sun, such that the panels are always perpendicular to the solar energy radiated by the sun. This will tend to maximize the amount of power absorbed by the PV systems. It has been estimated that the use of a tracking system, over a fixed system, can increase the power output by 30%-60%. The increase is significant enough to make tracking a viable preposition despite of the enhancement in system cost. It is possible to align the tracking heliostat normal to sun using electronic...

...be controlled with the help of 1-mega-ohm pot meter VR1. The AF output from IC1 is coupled to the base of transistor BD139 (T2), which, in turn, modulates the laser beam. The transmitter uses 9V power supply. However, the 3-volt laser torch (after removal of its battery) can be directly connected to the circuit—with the body of the torch connected to the emitter of BD139 and the spring-loaded lead protruding from inside the torch to circuit ground. The receiver circuit uses an npn phototransistor as the light sensor that is followed by a two-stage transistor preamplifier and LM386-based audio power amplifier. The receiver does not need any complicated alignment. Just keep the phototransistor oriented towards the remote transmitter’s laser point and adjust the volume control for a clear sound. To avoid 50Hz hum noise in the speaker, keep the phototransistor away from AC light sources such as bulbs. The reflected sunlight, however, does not cause any problem. But the sensor should not directly face the sun. DEPARTMENT OF ELECTRONICS AND COMMUNICATION ENGG, HARYANA COLLEGE OF TECHNOLOGY AND MANAGEMENT, KAITHAL-136027 1...
