INRODUCTION

The capstone project is to design, build and test “E-Street” is a prototype which controls the luminaries of street light with advanced lightning control system and low energy consumption. This report is prepared by Chirag Shah and Harsimran Singh, which delineate the contribution to project methodology, project management, and references for future projects.

Based on our research, energy loss due to street lights which consumes tremendous electric energy. Hence our goal is to develop efficient street lighting system with advanced technology to ensure conservation of energy. Our proposed model involves several components like solar panel, arduino mega, infrared sensors, LED’s, rechargeable battery, and etc. There are various advantages and benefits of this project which mainly includes lower cost, reduced maintenance cost, longer life and reduced risk of accidents since external wires are eliminated. The power consumption is one the most important merit of our model, because the power we are using is solar energy which is eco-friendly. This project can be applicable to all areas wherever street lights are needed, as an instance at streets, complex or any private campus, industrial area etc.

The basic frame of this report includes introduction, which describes purpose of the project. Introduction was followed by project description and methodology which explains every steps and phases of project in detail. The project management section scrutinizes details about scope statement, risk assessments, budget and Gantt chart. It also involves details of entire budget including labour rate and charges with discrepancies. In order to maintain budget and actual cost weekly SPI and CPI has also been calculated and recorded in EVA.

In nutshell, the project also comprises of recommendations and lessons learned section containing technical, cost and time lessons that team encountered. The conclusion and documentation summarizes our resources, contact information and links which can lead to online documentation.

PROJECT DESCRIPTION

This section will describe the entire technical functionalities of the project, such as outlined purpose behind the project and what obstacles came across during the project.

1. Technical Purpose :

Most of the time we observe that street lights are ON even after sunlight or when there are no automobiles identified on street. We all are well acquainted that in this era not only available energy is less but there is wastage of energy on enormous amount, this scenario of excessive loss of energy must be changed. To deal with the current problems, we have two best possible solutions for above mentioned problems. Usage of renewable energy source instead of conventional sources like and automatic control system of street lights with advanced technology are the two best solutions. Therefore, it is possible to begin a step ahead to turn street lightning system more dynamic with this model that has been developed.

2. Technical Problems :

There were several problems encountered during the project, but affirmatively it was figured out every possible way to find solutions. At initial stage after deciding the scope statement there was a dilemma to decide whether to use 555 timers, logic gates, microcontroller or arduino to control the system. Secondly, the toughest challenge was to decide rating of solar panel and to charge battery from it, whereby there were significant chances to get inconsistent and rippled voltage. Once it was decided to use arduino, the third obstacle that was encountered was its programming, where it could take a lot of time to program all basic requirements. Also the major challenge faced by us was with lightning functions, related to timing of Infrared sensors. Led started glowing before any of the vehicle interrupts the sensor.
