This design is the use of microcomputer with the sensor technology development and design of intelligent fire alarm system. Design purpose is to design and implementation of a distributed intelligent fire alarm control system, and the composition and realization of hardware and software. The main thesis of intelligent fire alarm system of the component parts have been introduced, its main control circuit and peripheral circuits interface between technology and software were also highlighted. Designed to MCS-51 microcontroller core for the hardware realization of intelligent fire alarm system . A selection MQ-2-type semiconductor Smoke Sensors detect smoke;optional digital temperature sensor DS18B20 Temperature measurement, use of the MQ-2 ADC0809 analog signals acquisition A/D converter for single chip processing. MCU processing data, and set the upper limit comparison, over the limit, give directions, to achieve sound and light alarm, to achieve the desired results.
