INTRODUCTION : 

INTRODUCTION Need for the project…….

Slide 3: 

It is also known as INCLINOMETER or CLINOMETER It is used to measure the slope of the device .

Basic Model of the System : 

Basic Model of the System Micro Controller (AT89C52) Oscillator Buzzer Driver Buzzer LCD -Display Accelerometer ADC (0809)

Basic Components used : 

Basic Components used Micro Controller (AT89C52) Accelerometer Analog to Digital Converter(0809) LCD-Display Buzzer and Buzzer driver Oscillator

Power Supply : 

Power Supply The incoming 230V ac is converting to +5v dc voltage using the below circuit… AC,230v

ACCELEROMETER : 

ACCELEROMETER Introduction….. Principle Types of sensing Techniques,,,,, Capacitive- Piezoelectric- Piezoresistive- Hall Effect- Heat Transfer-

Capacitive Sensing Technique : 

Capacitive Sensing Technique The capacitance equation How it sense the tilt ?? C= A /d

Equivalent circuit of accelerometer : 

Equivalent circuit of accelerometer

Measuring Tilt using a Two Axis Solution : 

Measuring Tilt using a Two Axis Solution We can measure the tilt using 2-axis or 3-axis Here we are using 2- axes to measure the tilt…

Basic calculations : 

Basic calculations The acceleration in the X-axis is calculated by the following equation: Ax=sin The acceleration on the Y-axis is calculated with: Ay = cos The acceleration of the object is calculated by: A= Ax +Ay Then the angle is Ax/Ay = sin/cos = tan  1g Ay Ax 2 2 2

Applications : 

Applications Industry : Machinery Health Monitoring. Building and structural monitoring Medical applications : to measure the depth of CPR chest compressions. Navigation: Inertial Navigation System (INS). Transport: To detect apogee . Sports: To measure the running speed.

MICRO CONTROLLER : 

MICRO CONTROLLER A microcontroller is a complete microprocessor system built on a single IC The microcontroller contains full implementation of a standard MICROPROCESSOR, ROM, RAM, I/0, CLOCK, TIMERS, and also SERIAL PORTS Popularly called "system on a chip" or "single chip microprocessor system" or "computer on a chip"
