Boot program can use any interface to download the application to the Flash memory area (Application Flash Memory). Application of Flash storage area is updated when the boot Flash area (Boot Flash Memory) program continues to run, RWW operation achieved. ATmega16 to bee a powerful microcontroller by 8bit RISC CPU and the system programmable flash in a single chip, for many embedded control applications provides a flexible and costeffective solution. ATmega16 has a set of programming and system development tools, including: C language piler, macro assembler, program debugger / software emulator, emulators and evaluation boards. B. Temperature Sensor Temperature sensor manufactured by DALLAS Semiconductor DS18B20type single intelligence temperature sensor, its performance features include: 1)This sensor have singlebusspecific technology, either through the serial port cable also through other I / O port lines and puter interfaces,without going through other conversion circuits Direct output measured temperature value (9bit binary number, with sign bit). 2) Temperature range is 55 ℃ ~ +125 ℃ , measurement resolution of 0. 0625 ℃ . 3) Containing 64 as amended through the laserreadonly memory ROM. 4) Fit a variety of SCM or system machine. 5) Users can set separate ways each temperature upper and lower limit. 6) Includes parasitic power. DS18B20 and the main chip connection diagram shown in Figure 2: DS18B20 number one pin grounded, then on the 3rd pin high and the 2nd pin then a 5. 1K of the pullup resistor, at the same time received a single output signal of the PD0 pin. Pullup is to pull the uncertainty signal through a resistor embedded in the high places, resistance at the same time current－ limited . Program from the DQ pin in high impedance state to ensure that the beginning, so that you can pull on the pullup resistor to the high DQ. At the same time the main chip also can be an external site alarm buzzer. Figure 2. ds18b20 and the main chip connection diagram. C. Smoke Monitoring Module Smoke sensors choose HIS07 ion smoke detectors when the flow through the inside and outside the ionization chamber ionization electron flow is unbalanced, collector charges current until the ionization balance. In a smokefree or nonbustion, the collector being subject to the impact ionization current statistical fluctuation, the potential to maintain a balance. Ionization current have impact when the smoke into the ionization chamber, easily into the ionization chamber smoke outside than inside the ionization chamber of the affected, ionization current decline in and collector to recharge until the new equilibrium potential, this potential change can be used to trigger the alarm circuit. Technical parameters such as Table 1.
