2. Introduction to Building Automation
Programmed, computerized network.
Electronic devices that monitor (logging of temperature, energy use, equipment start times, operator logon, etc) and control the building’s systems.
Reduced energy and maintenance costs – organize and optimize building control sub-systems such as security, fire/life safety, cooling/heating equipment, lighting control, etc.

3. Applications’ Examples
Automated security and surveillance systems.
Light and climate control.
Automatic plant watering and pet feeding.

4. Project’s Goals
Providing application programming interface for access to the intelligent building’s framework.
Providing wireless access to the intelligent building by PDA , Cell phone ,etc.
Implementation of a wireless distributed sensors network.

5. Technologies EIB – European Installation Bus
Communication System, with a set of physical communication media, a message protocol and corresponding models for the communication stack in each node.
Management system in the field of electrical installation for load switching, environmental control and security, for different types of buildings.
Can be installed in large buildings such as business premises, schools, hospitals and factories as well as in domestic residences.

6. Technologies cont. EIB Server
The EIB Server is connected to the EIB cloud via RS232 cable, the EIB server as its name suggests it serves as an interface to the EIB device, the transmission to the EIB hardware is made through Bluetooth devices.
The use of the EIB Server as a middle-man between the EIB and the outer world gives the user great flexibility in designing and building EIB setups.

9. Phase 1 - PEI 16 Serial Protocol
Connection
Asynchronous, serial and point to point.
Uses physical RS232 interface.
Full duplex with hardware handshake.
Four lines are needed – RTS , CTS , Tx and Rx.
Message Format
Consists of one length byte followed by 0 to 31 data bytes.
