2. Use
• Burglar alarms are automatic home
monitoring device to monitor and alert in case
of a burglary attempt at that place-house or a
commercial place.
• Our objective is to ensure security of property
using our device.

9. Acknowledgement
We would like to express our sincere
gratitude to Mrs. Barsha Das Mondal and
Mr.Aniruddha Sarkar for giving us the
opportunity to work with our desired
project under their guidance and patient
supervision.Their invaluable suggestion
and opinions have been a paramount
source of inspiration for us thepermision
to pursue the project which is mandatory
in the present B.TECH Curriculum.Last but
not at the least we would like to thank
each other for working hard as a group to
accomplish in due course.

10. CONCLUSION
Thus after months of research and
careful contemplation we as a group
came out with the idea of Burglar
Alarm.This document serves as the
blueprint of the culmination of our
ideas.The work of the project is
underway and ready to be completed
in the cource of time.
