CE 1.2.5 My responsibilities throughout the project
I have taken the responsibility to design a project on parking guidance using the wireless
sensor network. I have taken part effectively in making the automated parking guidance system
by utilizing the concepts learned in my engineering course of Electronics and Communication
Engineering. I have also taken the responsibility to execute the project in the required way. The
conditions and the technical features of the project should be implemented in an appropriate way
and it was also my responsibility to check all the operations and the functioning related to the
project. The information from the internet and several articles, journals, and books have been

the project are true and are relevant to the project.
CE 1.3 Distinctive Activity
CE 1.3.1 Comprehension of the theory of the project
This project was designed to create a project based on parking guidance using the
wireless sensor network. The main components for these projects are Atmel 89S52
microcontroller, LM7805 voltage regulator, 433Z RF transmitter, 433 MHZ receiver, RF
encoder and the HD44580 LCD. The main theory behind this project is related to the
microcontroller, LCD, voltage regulator and the transmitter. This project requires the concepts
related to sensors. The primary function of the sensor is to measure a physical quantity which
can be converted into any type of required signal. In this project, the sensor was used to get the
input from the position of the car and then the input was converted to a required electrical signal
and was sent to the micro controller. Then the microcontroller was used to analyze the data

according to the coding. The voltage regulator was used to provide the required amount of
voltage needed for the system to work properly.

CE 1.3.4 Identified issues and their solutions
1.3.4.1 Issues
During making this project I have faced various issues. There was a broad range of
problems which were faced regarding the circuit connection.
 An issue related to the microcontroller used in the system is that this can malfunction
due to overheating and also sometimes the threads can make the microcontroller
system work in a wrong way.
 The voltage regulator and the display system can also be malfunctioned due to the
cause of overheating.
 The sensor can also deliver a sluggish response due to bad sensitivity.
1.3.4.2 Solutions
 To avoid this solution, appropriate planning was needed. The main advantage of
designing the circuit was that it should be pre-planned and in that case, the possibility
of errors is limited.
 To overcome the issue related to the overheating of the microcontroller, proper heat
sink should be used in the microcontroller. I have also designed the microcontroller in
such a way so that the minimum number of threats can take place in the system.
 The voltage regulator and the LCD display system should be better quality so that
these should not have any kind of malfunctioning during the implementation of the
project.
 The sensor should have proper sensitivity.
