Abstract

Wireless car notification system; is mainly about having information regarding the car, to be updated around the hour and be displayed to the user.

By using a number of different types of sensors, to get an important information regarding the car, which are transmitted using transceivers between the implementation of this project in the car, and a remote that has an LCD, which displays those updated information.

Knowing and getting information about the user’s car can make the user start a certain action depending on what is showed on the LCD screen.

CHAPTER ONE

INTRODUCTION
1.1 Overview of the sensors
A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, most sensors are calibrated against known standards. Another example The LM35 converts the temperature into a voltage that we can measure it using the voltmeter.

A good sensor obeys the following rules:
* Is sensitive to the measured property
* Is insensitive to any other property likely to be encountered in its application * Does not influence the measured property

Here we used different ways to achieve our goals. We used the LM35 sensor for the temperature. For both, the fire sensor and the light sensor, a Light Dependent Resistor (LDR) was used. And used a simple switch sensor that has does the job of the motion sensor, and have the same concept of it.

1.2Project Objectives

In this project, our goal is to monitor the car by using different types of sensors.

Using the microcontroller PIC to coordinate between the elements used in this project, then to be sent through a transceiver.

The information are received by the transceiver set in the remote of which the user has in hand. The information are then to be displayed in an LCD screen attached to the same remote, showing and notifying the results of monitoring the car.

1.3Project Outline
The project consists of four sensors, transceivers,PIC16F877A MCU, and LCD. Each of these components is connected with PIC16F877A in certain way according to its design.

After programming the PIC, and doing the implementation of the sensors and other components, we tested it.

This project is highly based on the PIC16F877A, it’s based in the programming used to the PIC, which will control and gives us the results that needed.
