The user will communicate to raspberry-pi through wifi
network. The system is flexible and scalable, allowing
additional home appliances designed by multiple
vendors, to be securely and safely added to the home
network with the minimum amount of effort. the wifi
network should be having adequate strength also. we can
use a wifi-modem for steeping a wifi. the user can have
a nice android interface for using the system. The serial
data coming from wifi unit is connected to raspberry-pi
circuit. The core of the home automation system
consists of raspberry-pi board. it can be viewed as a mini
computer capable of doing many functions. The
raspberry-pi board is configured for each home
appliances .so according to user intervention the
matched out will make high and the corresponding relay
will switch on and device start function. The system is
scalable and allows multi-vendor appliances to be added
with no major changes to its core. This project mainly
consist of three modules as follows.
