As
usual, I thought of numerous ways to improve this
project even before I finished. For instance,
integrating an Ethernet interface and TCP/IP stack
will allow for a web server that can be checked
from anywhere via an Internet connection. And
since text messages can be sent to some cell phones
by e-mail, this will allow alerts to be sent right
to a cell phone.
Additional
sensors will greatly expand the system’s capabilities.
I want to design a sensor that can check the position
of a deadbolt lock, perhaps with a metal detection
circuit. I also want to add smoke, carbon monoxide,
and combustible gas sensors. A sensor that can
detect when burners on my kitchen stove are in
use would be useful too.
