INTRODUCTION
These days many problems are solved
by using electronic devices which detects and controls the errors up to some
extent. Many of the problems are handled using robots.
“FIRE SENSING ROBOT” is a project
used to detect fire automatically in a hall like space. Here the robot detects
the fire and moves near to it and tries to pour water. If it is not able to
control the situation, then it ON the buzzer and sends SMS to the predefined
numbers.
DESRIPTION
In this project we are developing a
robot which detects the fire automatically. Here we are using an LDR (Light
Dependent Resistor) to detect fire. The output of LDR is a resistance variance
dependent on light. This resistance is converted into voltage and taken into
ADC. ADC converts the analog voltage into digital bits which is taken into
microcontroller. Microcontroller controls the motion of the motor and moves
towards the fire. Once it reaches near to the fire, after few seconds it sends
an SMS to the predefined numbers.
8051 architecture based P89V51RD2 microcontroller
from NxP is used to implement this project. Microcontroller acts as the heart
of the project, which controls the whole system. It contains 1k RAM, 64k Flash,
3 Timers, 2 external interrupts, 1 UART, 32 GPIO’s, ISP programming support
etc. KEIL IDE is used to program the microcontroller and the coding will be
done using Embedded C.
