OBJECTIVE
The robot is developed to give an alert when any fire
accidents occurs and to give alert when there is no
sufficient light. An advent of a new way of control using
mobile has been implemented in this project.

INTRODUCTION
In early days, robotic manipulators have been implemented indifferent control techniques like mechanical control and theremote control or tele-opertation. But with the advent of high
performance, a new way of control using mobile has been
implemented which is introduced in this project. The fire detection scheme to be put into use is relatively free
of false alarms, it is anticipated that it will not overreact innon-fire simulations.
The light sensor can be operated in two modes: with itsinternal red light source on or off. The light sensor is onlycapable of detecting absolute light intensity

The SensorsFIRE SENSOR:
Sensors were needed to detect vicinity of candle flame, exact
location of candle flame, and robots proximity to maze walls.
the robot would be able to sense an object in the front left,
front center, and front right. in order to detect the flame we
will need to calibrate it to detect the flame of a candle.

LIGHT SENSOR:
LIGHT DEPENDENT RESISTORS:
LDRs or Light Dependent Resistors are very useful especially
in light/dark sensor circuits.

BUZZER
A buzzer or beep is an audio signalingdevice, which may be mechanical, electro
mechanical, or piezoelectric. Typical uses of
buzzers and beepers include alarms, timers
and confirmation of user input such as a
mouse click or key stroke.

DRIVING CIRCUIT
DPDT RELAY:
DPDT stands for double pole double throw relay. Relay isan electromagnetic device used to separate two circuits
electrically and connect them magnetically.

GARE MOTOR
The direction the shaft rotates can be changed on most motors
by switching the right wires, there is usually a diagram on the
motor.
The direction of rotation is usually determined by viewing themotor from the shaft end and is designated as CW (clockwise)
orCCW (counter-clockwise).

FUTURE SCOPE
A practical fire and light sensing robot system must include a
collection of robots.
communicating and cooperating in the mission and system
requires facilities for going through obstacles in the presenceof fire.

CONCLUSION
Detects fire and light intensity.
To reach the current sensor network and mobile agent
technologies.
To replace the human with an automated mobile agent.
