10. WORKING OF THE PROJECT
Proteus design:-

11. Programming

13. Working Principle of Motor
Demonstrate various variables linked to the
PIC16F887 microcontroller. To the
microcontroller we connected the heat sensor,
which work as sensing device.to other end
motor driver L293d H-bridge installed which
perform as driver of the submersible pump in
output port of the L293d submersible pump is
connected which is use for the spraying water
on burn flame. For the controlling the Hz
frequency we use the oscillator and capacitor.
As a power supply of the model, we use
external power supply 12v.

14. TROUBLESHOOTING
During the selection of sensor we face which is best for our project.
Problem with the calculation of temperature from sensor output in
program.
Use of Motor Driver L293D.

15. APPLICATION
Easily extinguishes the area where explosion of heat is high.
Suitable for a fire department.
Use in Chemical industries without interfering the human beings.
Time consuming during the explosion of fire.

16. ADVANTAGES
To detect the exact direction of the fire source.
Reduce the human effort.
Reliable and economical.
Not sensitive to weather conditions.
Efficiency of model is high.

17. DISADVATEGES
No monitoring system for the robot.
It is not use when the fire is in large area.
Sensing range of sensor is up to 1 Ft so no sense more than 1 Ft.
Only sense the fire in between the 60° angle.

18. FUTURE SCOPE
With improvement in design we can use during Wildfire.
With use of sprinkler we can cover vast area of fire.
Instead of water we can use CO2 or liquid N2.
With use of camera we can easily monitor fire area from any place.

19. CONCLUSION
Our project is main focused on reduce the hazardous situation in
fire. In our project we have made and implement modular design of
extinguish fire and reduce hazardous situation during fire fighting. With use
of microcontroller we integrate it and made it simple.
