This study is focused on designing an expert
system for home appliances by using wireless sensors which can
help the common people to repair the frequent problems of home
appliances. In general, people are having very little knowledge
about the home appliances. They used to contact to the service
providers or vendors for solutions. But many times the problem
is very minor and still it consumes both money and time because
of lack of knowledge among people about home appliances. In
this paper a combination of expert system with wireless sensors is
proposed to solve such kind of minor problems in home
appliances. In the proposed framework the wireless sensors are
installed with different home appliances in different regions of
the home. Whenever problem occurs in any part of home
appliance, the sensor detects that problem automatically and
sends it for solution to the expert system. Various noise removal
algorithms for removing noise from the received data can be
applied for getting noise free data. The expert system finds the
solution based on the type of problem and sends the solutions
with various images through SMS or e-mail to user's mobile or
mail-id. If expert system detects that problem is unsolvable or
cannot be easily solved by that user then it sends a list of contacts
of user's nearest service providers or vendors so that user can
contact to them. For example in refrigerator, if sensor detects
that freezer is failed then the expert system will send the solution
to the user that "kindly check the control dial of temperature".
