Group 1 Illumin-IT

Group members:

Scenario and motivation:

In Northern countries, summer have longer days and the sun rarely shines on dark winters. Our idea is to maximize the use of natural light by complementing the light.

SUSTAINABILITY

Save energy using automatic control with presence and movement sensors

Dim and control light intensity with response to natural light

Extend product life cycles for light bulbs

Improve productivity and well-being of people in rooms

PROOF OF CONCEPT

Using the DHS HomeManager and FS20 sensor/ control modules. Our group plans to control the lighting inside rooms based on natural light intensity outside.

To maximize the use the natural light, we dim the indoor lighting when the sun shines brightly and so on.

Using a movement/ presence sensors, lights will only turn on/ off.

ZigBee Protocol Overview

What is ZigBee protocol?

Emerging standardized protocol for Ultra Low Power Wireless Personal Area Networks (WPANs);

an established set of specifications for wireless personal area networking (WPAN) i.e, digital radio connections between computers and related devices;

ZigBee is targeted at radio-frequency (RF) applications which require a low data rate, long battery life, and secure networking;

How ZigBee works?

The following figure depicts zigbee protocol stack,which consists of four layers:

The application layer: highest-level layer defined by the specification and is the effective interface of the ZigBee system to its end users;

The network&security layer: enables the correct use of the MAC sublayer and provide a suitable interface for use by the next upper layer and provides 128 bit AES encryption key for communication on PAN(Personal Area Network);

MAC layer: used by zigbee devices to establish connection to the PAN by exchanging system information;

Physical layer: ZigBee builds on this layer and media access control defined in IEEE standard 802.15.4 for low-rate WPANs.

Why ZigBee?

Advanteges	Disadvantages
Open Standards	Interference with other devices
Low cost	Slow market expansion
Easily deployable and global
Reliable, secured and self healing
Supports large number of nodes
Very long battery life

Application Sectors:

Li-Fi technology

Introduction

LiFi is a wireless optical networking technology that uses light-emitting diodes (LEDs) for data transmission.

LiFi is designed to use LED light bulbs similar to those currently in use in many energy-conscious homes and offices.

However, LiFi bulbs are outfitted with a chip that modulates the light imperceptibly for optical data transmission.

LiFi data is transmitted by the LED bulbs and received by photoreceptors.

Advanteges	Disadvantages
Sufficient usage of RF BW	Light can't pass through objects
High data transmission rate (10Gbps)	Internet can't be used without a light source
High level of privacy & security
Low implementation and maintenance costs

Future work

As a future work we can propose a novel approach which controls electric indoor lighting, such as LED lights using photo-voltaic system integrated into an office building.Based on the amount of available daylight, we can calculate the amount of artificial illumination required with the reference indoor illumination, and we can also control the indoor lighting without the need for indoor photo-sensors.
