Through the main controller the room temperature and

humidity measured data can be

retrieved also from remote

user via Internet browser. After remote user connects this

main PLC controller via Internet, a web page will

displayed on the user’s computer (fig. 14), and then the

user’s operation is similar to the operation on the main

PLC controller’s screen.

Figure 15 shows an experiment to switch the

conventional electrical fan on or off by a PLC device

controller on the home network.

V. CONCLUSIONS AND FUTURE WORKS

This work is to utilize the home electrical system for

networking, the implementation of a home appliances

control system based on the PLC technology has been

successfully deployed. Authorized manager can access the

main PLC controller to control the selected home electrical

appliance or monitoring sensor’s data locally or from the

Internet.

The user’s interface is quite convenient, via internet

web browser from any platform to access this system. Data

security also provided to protect the system from

unauthorized access.

Although this system can process some simple tasks

at this moment only, but it can be extended further for

some additional functions, such as video camera and

burglar alarm for enhance home security or automatic

timer control for saving energy.
