MICROCONTROLLER BASED FIRE FIGHTING ROBOT

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

PROJECT OVER VIEW

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

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.

POWER SUPPLY

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

LINEAR POWER SUPPLY ► TRANSFORMER ► RECTIFIER ► CAPACITORS ► LED ► RPS

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

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

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.
