1.1 THE AIMS AND OBJECTIVES OF THE PROJECT
For a
security system with various alarm outfit and various security
detectives device. These devices may detect various faults according to
their function, and might also cause alarm to alert the security
personnel. But the simultaneous alarm alert, may result to Unisome and
Chios in a bid to differentiate sound differences and what type of fault
was detected.
This puzzles led to the use of a microcontroller in
combination of a smoke detector. Now with the help of this new
development, a screen display is design and actualized via construction
process to achieve this aim. By the display on the screen the security
personnel can easily sort-out what type of detector are alerting him or
her, and which of the detected fault needed fast response.
1.2 PROJECT OUTLINE
The
design and construction of a microcontroller smoke detector is divided
into four major section which are the regulated power supply, the
control section, the display section and the smoke detector unit.
1.2.1
The regulated power supply was use to power the circuit, it was
regulated because digital IC’s were involved in the circuit and these
digital IC’S work on a regulated power supply.
1.2.2
The control section is where the processor involved in this design was
control. It includes the 89s52 microprocessor and crystal oscillator.
The 89s52 control the programme code is the Rom and other component
around it. The crystal is used by the 89s52 to synchronize it operation.
1.2.3
The screen which we use in this project was the dot matrix display
system this involve the arrangement of LED is Rows and column by
considering the cathode and anode connection, to achieve organized
display of character as programmes are decoded by the decade IC’s and
forms character on the screen.
1.2.4 The smoke
detection plays an important function because it acts as a switch to the
entire system. It senses smoke with the help of the LDR light dependent
resistor and the LM324 IC comparator to switch the microcontroller to
start booting up and executing it programmes.

ABSRACT - [ Total Page(s): 1 ] 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 ... Continue reading---
