i am project student, my project is to Design and construction of a home alarm system. Maybe
p.c. based or standalone (using PIC or other cheap micro-controller).
Audible alarms will sound off in event of an
intrusion, but may be modified to include a text-message via
a modern/mobile phone to warn the owner. Software mainly,
may also involve interfacing issues i.e. how to link with
sensors (on-off switch or other proximity or infra-red sensors).
Should aim for flexible system and low cost using existing
components. can you please send me the neccessary information as soon as possible?
Thanks.
