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.

AcknowledgementWe 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.

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.
