In proposed system, wireless sensor

In proposed system, wireless sensor nodes and one cluster
node are designed. Both sensor nodes will sense the light and
will communicate with the cluster node. The cluster node will
then communicate with the computer via serial interface. The
computer is connected with the external device.The device
may be laptop, mobile, etc. A software application will be
used to read and write data to and from WSN node over serial
communication. This complete scenario will then connected to
web interface / application to let the user communicate with
the WSN head using internet from anywhere.
