3. ➢ Home appliance control system is based on GSM
network technology.
➢ SMS sending and receiving is used for ubiquitous
access of appliances and allowing breach control at
home.
➢ This project mainly focusses on the controlling of home
appliances remotely.
➢ The system is wireless therefore more adaptable and
cost-effective.

5.  Now a days,GSM service is easily available to
everyone.
 You need not to carry a different remote.
 It is used to send SMS.
 It provide serial interface.
 Can be controlled through serial AT commands.

8.  Power conservation
 System can be operated in manual mode.
 Easy to use.
 Economical.
➢ Make life easier.
➢ Security.
➢ Design is small and portable.

9. ➢ The receiver must reside where sufficient signal can be
received from a cellular phone network
➢ The receiver must have a power supply at all times
➢ A limited number of device can be connected to the
sysytem

11. ➢ GSM technology capable solution has proved to be
controlled remotely, provide home security and is cost-
effective as compared to the previously existing
systems. Hence we can conclude that the required goals
and objectives of WHAS have been achieved.
➢ By this project we can control our home appliances and
also we can avoid the unnecessary electricity bills by
giving the response to microcontroller.
