INTRODUCTION


MEMS : Micro – electro-mechanical systems

Combination of mechanical functions (Sensing,

moving, heating) and electrical functions (Switching,

Deciding) on the same chip using micro fabrication

technology

AIM:-

The aim of the project is to display the advertising on LED

panel and to change direction of advertisement display on

LED panel by using MEMS technology


PURPOSE:-

The main concept we can control the home

applications automatically using MEMS technology

nothing but GESTURE BASED.

We can save the man power.

We can reduce the time concession.

DESCRIPTION:-

In this project we are using MEMS technology

and LCD.

MEMS means Micro Electro Mechanical Systems.

The project constitutes a microcontroller, MEMS

Accelerometer and LCD.

Normally the advertisement displays in the predefined

orientation or direction.

If any change in the direction of MEMS will change the

display direction of the advertisement on the LCD


TECHNOLOGY:-

MEMS TECHNOLOGY:

MEMS are free scale’s enabling technology for

acceleration and pressure sensors.

MEMS based sensor products an interface that can

Sense, Process or control the surrounding environment.

MEMS-based sensors are a class of devices that builds

very small electrical and mechanical components on a

single chip.


SOFTWARE AND HARDWARE TOOLS

SOFTWARE TOOLS:-

Keil

Proteus

Embedded c

HARDWARE USED:-

Microcontroller

Power supply

LCD

MEMS technology


APPLICATION OF MEMS


In Medical Field:

A MEMS device can be implanted in

the human body

MEMS surgical tools provide the

flexibility and accuracy to perform

surgery

Transducers

ADVANTAGES:-

Cost-efficiency.

Low power consumption.

Miniaturization.

High performance and integration.

Functionality can be integrated on the same silicon or

in the same Package, which reduces the component

count.

This contributes to overall cost savings.


DISADVANTAGES


Farm establishment requires huge investments

Micro components are costly compared to

macro components

Design includes very much complex procedures

CONCLUSION:-

By using this project we can display advertisement on

the LED panel and change the direction of

advertisement display on LED panel by using MEMS

technology.

The enabling technology premises to create entirely

new categories of products.

Mems will be the indespensible factor inadvancing

technology.

As with all emerging tecnologies had been predicted to

revolutionize technology and our lives.
