Resulting from several stages of circuitry
soldering tryouts, Fig. 4 shows our hardware
implementation—a basic communication
module, wireless outlet, wireless switch, and
wireless passive infrared (PIR) module. In particular,
the basic communication module functions
as the dongle and a constituent block of
wireless outlets and switches. Our wireless outlet
mounts two sockets for powering home appliances.
A rechargeable battery inside is fitted out
to power the circuitry on the wireless outlet in a
self-reliant manner.
