33. Conclusion
The Project provides us the ability to control any house
hold electrical equipment anywhere from the world. The Project
is also focused on anti-theft & security to places that are prone
to gas leakage , the device is equipped with the most advanced
MQ-6 Gas sensor which detects smokes which are of commercial
use in wide range of places. It also senses/detects activity
around 20 meters from where the device is mounted. The user is
notified through SMS & internet if any of these changes are
detected in the preferred location. With prior to detection of
motion user is requested to activate alarm through 4 digit
passcode which is encrypted with SHA-256 algorithm.
The Project is aimed at providing global security to the
upcoming generation with the power of Cloud & Electronics.
