Abstract
The home automation becomes important, because it gives the user the comfort and ease for using the home devices. The implementation and design of wireless home automation control use two methods, WLAN technology and RF remote control handheld to control selective home devices with integral security and protected system. The devices have been distributed in two rooms, each room has own board, these boards are connected to the desktop personal computer (PC) through one serial port RS-232 via microcontroller. The software consists of Assembly Language for programming microcontroller (AT89C51and AT89C2051) and Visual Basic Language that use to communicate between PC and two boards, also it use to design Graphical User Interface (GUI) which involving all devices needed to display in Home PC screen . The system is low cost and flexible with the increasing variety of devices to be controlled.
Highlights
The home automation is control of home devices from a central control point, automation is today’s fact, where more things are being completed every day Mahmood S
The popularity of wireless networks in home has increased in recent years, and the advanced computer technology has made the personal digital device to commonly have the capability to communicate through the wireless network
It is suitable to use RF-based location determination system to estimate the location of the personal digital device in a home environment with high data rate transmission, supporting multimedia applications may be feasible in WLAN [3]
Summary
The home automation is control of home devices from a central control point, automation is today’s fact, where more things are being completed every day Mahmood S. Imagine a private home equipped with motion, light, temperature and other sensors and actuators for opening the door, dimming the light, controlling the heating and so on [4] It can be as basic as dimming lights with a remote control or as complex as setting up a network of items in your home (such as a thermostat, security system, lighting and appliances) that can be programmed using a main controller [3]. The WLAN System Design This section focuses on the hardware part, which consists of designing two boards, RF remote control, WLAN (802.11g) and sensors These two boards are connecting to the desktop Home PC through one serial port (RS-232) as shown in figure (1). The second board ( board 2) as shown in figure (3) consist of several components such as Microcontroller (AT89C2051), MC1488, MC1489, 47LS244, 74LS374, ULN2803 and comparator, the board 2 function is to control room devices with protected system through WLAN and RF remote control handheld. The Lamp and Fan in board are connected to the output Green LEDs in order to show the user in the home that the devices are operating properly
