What is HACS?

• Home Appliance Control System accessed by a remote device such as mobile phone or a palm-top to allow a home owner to control, monitor and coordinate home appliances.

How it happens

Why HACS ???

When: you are in a traffic jam on the highwayWhat: You set microwave oven in a slow cooking mode

Slow cooking mode

1. Saves time2. Save money (Long run)3. Self Maintenance4. Security5. Makes life easy

Overview of HACS System

Database

Accessing It• Input device • User Interface – Login, Initial Settings,

Operations, Logout

Interaction with HACSThe user can interact through any input device such as

the Laptop, Palmtop, Cell phone etc..• The user interface allows the user to enter or tell the

user name and password.• The user can also provide fingerprint or retinal scan for

authentication.• The system then transfers the details to the

authentication server and the authentication server allows or denies the user according to the information provided.

• After Authentication, the user is allowed access into the system

System Design• HACS is a system which is controlled by a remote

system such as a cell phone, and controls home appliances such as VCR

• In case of emergency such as fire, the user or an organization such as Fire Department should be notified.

• Also, HACS should have a database of information about the users and appliances.
