1.4. SCOPE OF THE PROJECT
This project is focused on designing and
constructing of an automated light system using photo-sensitive switch.
That is, to illuminate the case study in response to change in weather.
The system comes on at twilight through the night and goes off at dawn
all through the day. The project research work covers the following
photosensitive devices like light dependent Resistor (L.D.R) which
serves as the sensor. It x-rays the design calculations of the basic
circuit parameter and other areas of applications of this system. It
also lays great emphasis on passive and active components like Diode
Resistors, capacitors Darlington pair transistors, electromagnetic
relays, lamps and transformers.
1.5. OVERVIEW OF THE PROJECT
The
high rate of technological advancement in industrial automation,
security and control motivated me to embark on a project research work
on design and implementation of automated light system using
photosensitive switch. This electronics system is designs in five
different modules all combined to form one functional unit. The first
module is the sensor (light-dependent-resistor). Its output is
conditioned by an RC-network (delay circuit) that forms the second
module. The third module is the driver realized with Darlington pair
transistor. The fourth module is the electromagnetic relay where the
fifth and final module –load are interfaced. The result being a rugged,
robost and easy – to – maintain system.
1.6. PROJECT REPORT ORGANISATION
This
project is presented in six chapters to appropriately illustrate the
steps involved in its design and implementation. Chapter one introduces
the designs objectives, general introduces the design objectives,
general description of the project and significances of the project.
Chapter two is fundamentally the literature review and issues relating
to its implementation. Chapter three confers the system methodology and
analysis. Chapter four elaborates on the system design and analysis.
Chapter five x-rays the implementation and testing. The sixth and last
chapter summarizes the project theories conclusion and recommendations.
