  2. ABSTRACT The object of this project is • IN OUR PROJECT WE DESIGNED A PROTOTYPE TO DETECT FIRE AND EXTINGUISH THE FIRE WITH THE HELP OF WATER SPRINKLER

  3. PROJECT OVER VIEW

  4. Power Supply +9 V & +5 V AT89S52 SMOKE DETECTOR BLOCK DIAGRAM WATER SPRINKLLER VISUAL INDICATOR

  5. Project Explanation • BRAIN OF THE PROJECT IS MICROCONTROLLER. • IT INTERFACE WITH SMOKE DETECTOR AND OUTPUT. • DETECTOR GIVES SIGNAL TO PORT3 OF MC. • IT PERFORM 4 ACTIONS.

  6. POWER SUPPLY

  7. Power supply types • Linear power supply. simple design that becomes increasingly bulky and heavy for high current devices . • switching power supply. Itis usually more efficient, but will be more complex.

  8. LINEAR POWER SUPPLY • TRANSFORMER • RECTIFIER • CAPACITORS • LED • RPS

  9. AT89S52 MC • Architecture – 8051 based • 8-bit Microcontroller • 8K Bytes In-System Programmable Flash

  10. Features • Fully Static Operation: 0 Hz to 33 MHz • 4.0V to 5.5V Operating Range • 256 x 8-bit Internal RAM • Full Duplex UART Serial Channel • Fast Programming Time • Eight Interrupt Sources • Dual Data Pointer • Three 16-bit Timer/Counters

  11. Description • The AT89S52 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications. • The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry - standard 80C51 instruction set and pin out.

  12. PIN CONFIGURATION

  13. PIN DESCRIPTION • VCC • GND • Port 0 • Port 1 • Port 2 • Port 3 • RST • ALE/PROG • PSEN • EA/VPP • XTAL1,XTAL2

  14. SMOKE DETECTOR • Make – MOSDESIGN SEMICONDUCTOR CORP. • This device can be used in conjunction with an infrared photoelectric chamber to sense scattered light from smoke particles.

  15. FEATURES • Interconnect up to 50 detectors. • Piezoelectric horn driver. • Power-on reset. • Built-in circuits to reduce false triggering. • 6V to 12V operating voltage range. • ESD-Protection circuitry on all pins. • Temporal horn pattern.

  16. PIN CONFIGURATION
