ABSTRACT

The microcontroller smoke detector is a system designed to provide security level in areas that requires high accuracy of precaution against fire outbreak, in an industry, commercial buildings and even domestic homes.
This project uses 89s52 microproecessor as it major component. This microprocessor is the central processing unit of the project, it is configured into the design and function of a microchip which is some times refers to as logic chip. The microprocessor IC stores programmes and has general types of memory example on-chip memory, which hold actual programme that is, to be run this IC has a memory capacity of 8 kilobytes. The programmes are burned into it, as ROM or EPROM it programme may equally be stored via on external ROM.
When the detector senses the present of smoke which creates a dark shadow, it alert the microcontroller which is the C.P.U, causing on alarm and equally fetching programme which are stored and executing them by making the light emitting Diode to display noticeable character for any security officer, in order to find any fast and immediate solution.

CHAPTER ONE
INTRODUCTION
1.0   THE BACKGROUND
        In past decade there have been cases of fire outbreak, in our commercial building domestic houses and our industries. Possible causes of fire out break are as a result of faulty electrical installations, carelessness over faulty maintenance and lack of oventations on fore outbreak. The reason while fire in always able to engulf our household or industry are as a result of poor security system or bad (faulty) fire security system. Owning to all these, it is of a paramount important to include a smoke detector in our security system which I do advice should also be in co-operated with a microcontroller display unit.
        This project design is the simple use to display visible write up on the screen a with on alarm which simultaneously alert the security officer the present of smoke, either from any electrical equipment, connection or any burning material, needed to be extinguished before resulting to a fire outbreak. The major component used in this design are the 89s5$ microprocessor, crystal oscillator, Electronic switches light emitting diodes, IC decoders and sensor. Some other common and readily available component like the transformer is very necessary as regards to power supply.
        The micro-process is the central processing unit in the project. It helps to fetch, programme form it memory, and execute the action.
        A dot matrix display made of light emitting diode (LED) is use to display the information contained in the programme. The information display is in a form that can be understood by the uses or operator.
