BUILDING LIGHTING AUTOMATION THROUGH THE

INTEGRATION OF DALIWITH WIRELESS SENSOR

NETWORKS

ABSTRACT• This paper focuses on the integration of Digital Addressable Lighting

Interface (DALI) devices in wireless sensor networks.• Since different manufacturers usually deal with one aspect of

building automation - e.g. heating ventilation and air conditioning, lighting control, different kinds of alarms, etc. - final building automation system has different subsystems which are finally taken to an integrated building management system.

• The cost of this process is consequently increased due to additional hardware investment.

• Our main purpose is to provide the end consumer with an economical fully centralized system in which home appliances are managed by an IEEE 802.15.4-based wireless sensor network

• . Not only is it necessary to focus on the initial investment, but maintenance and energy consumption costs must also be considered.

EXISTING SYSTEM

• wired net works used

• High cost.

• Network extensions limited.

• Limited features.

• Complex network protocols (like x10,BAc).

PROPOSED SYSTEM

• Our main purpose is to provide the end consumer with an economical fully centralized system in which home appliances are managed by an IEEE 802.15.4-based wireless sensor network

SERIAL DATA COMMUNICATION

• MAX232 is used here to interface zigbee with microcontroller

• The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator to supply RS-232 voltage levels from a single 5-V supply.

• Each receiver converts RS-232 inputs to 5-VTTL/CMOS levels.
