Homeautomation

iHome Security & Automation System

Home Automation System Home Automation is a field specializing in the specific automation requirements of homes and in the application of automation techniques for the comfort and security of its residents.

Home Automation
HAS can also be defined as remote or automatic control of things around the home.
An automated home is an intelligent home and an interactive home that takes care of mundane activities, leaving you with enough time to indulge in other activities

Smart Home has been “coming” for 30 years – Why Now..??
Emergence of wireless technologies for home automation solutions
Wireless broadband is mainstream
Increasing awareness among customers
Lower equipment prices and installation costs

Home Automation Systems
Security
Heating, Ventilation and Air Conditioning (HVAC)
Lighting control systems
Audio
Video
Intercoms
Robotics

The elements of a domotics system are-
Controllers
Sensors
Actuators

Hardware Overview
The automation system will use four levels of ‘nodes’ to control different aspects of the automation system-
Level 0
Level 1
Level 2
Level 3

iHome Security & Automation System iHome Automation Overall Flowchart

Hardware Description-Level 0 Nodes
Features controlled by Level 0 nodes are mostly sensors, such as sound, temperature, photo cells, and security.
Level 0 nodes will not have a user interface, and they connect to the system through L1 nodes.

iHome Security & Automation System L1 Device Interface
Eight TTL Output Ports (5V)
Four TTL Input Ports (5V)
Three Analog Input Ports (3.3V)
Four PWM Output Port (5V, resolution of 33,300)
127 Channel I 2 C Port (3.6V)
Two SPI Ports (3.6V, 1mbps)
One digital quadrature encoder input (5V)
All L0 Nodes connect to the system via L1 nodes using the following L1 ports:

Level 1 nodes connect to the system by either X10 cable or wirelessly.
Level 1 nodes control Level 0 nodes and provide a user interface for these nodes.
iHome Security & Automation System Hardware Description-Level 1 Nodes

The Base Station bridges the central server to the L1 node network.
It connects to the central server using USB, and then connects to the rest of the L1 nodes via Cat5 cable (RS-485 signaling) and wirelessly.

Level 2 nodes are designed for audio / communications, and have no user interface.
Features controlled by these type of nodes include : audio/entertainment playback (MP3 and WMA format), 2-way intercom operation, etc.
These nodes connect to the central server via Ethernet, and are individually powered.

Level 3 nodes may or may not (depending on time constraints) be included in home automation.
Level 3 nodes are used for streaming video between the central server, TVs, and video cameras.
Level 3 nodes do also not have any type of direct user interface.

By wire :
DSL(digital subscriber line)
Optical fiber cable

Radio frequency -Wi-Fi ,GPRS ,Bluetooth and infrared
3. Both

What is X10?
X10 is a communications "language" that allows compatible products to talk to each other using the existing electrical wiring in the home
X10 is a standard for communication among electronic devices used for home automation, also known as domotics. It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information.
