ABSTRACT

This project presents the possibility of using electronic components to produce a safely device. The device is a smoke detector which has been constructed using components such as resistors, diodes, capacitor, integrated chips (ICs), transistors, microcontroller (AT89552), buzzer etc. It is a photoelectric type ofsmoke detector that employs the principle of conservation of energy and the kinetic theory of gases. The circuit is divided into four main units. Viz: power supply unit, smoke sensing unit, control unit, light and alarm unit. To ensure a steady supply of power to this device, 220volts a.c supply and a volts battery was used to supply, power. The device provides an early warming alarm when there is the menace of fire outbreak.
