TRIPLE AXIS ACCELEROMETER(ADXL345)

                                 The triple axis accelerometer is used to sense the tilt in position on three dimensional axis.The ADXL345 is a small, thin, low power, three-axis MEMS accelerometer with high resolution (13-bit) measurement. It measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock. We can interface tilt sensor with Arduino to automatically identify the tilt. 

                                 

Application:

• Accelerometer is used for motion sensing.
• It is used in navigation analysis.
• It can be used in GPS with e-compass systems.

Sample Project With Arduino:

                                    In this we going to identify the axis i.e. to know the position like whether it is in landscape or portrait using the ADXL 345 sensor.

Materials required:

• ARDUINO UNO
• ADXL345
• Bread Board
• Jumper wires

Circuit:

Code:

#include<wire.h>

#define accel_module (0x53)
byte values[6] ;
char output[512];

void setup(){
Wire.begin();
Serial.begin(9600);

Wire.beginTransmission(accel_module);
Wire.write(0x2D);
Wire.write(0);
Wire.endTransmission();
Wire.beginTransmission(accel_module);

Wire.write(0x2D);
Wire.write(16);
Wire.endTransmission();
Wire.beginTransmission(accel_module);
Wire.write(0x2D);
Wire.write(8);
Wire.endTransmission();
}

void loop(){
int xyzregister = 0x32;
int x, y, z;

Wire.beginTransmission(accel_module);
Wire.write(xyzregister);
Wire.endTransmission();

Wire.beginTransmission(accel_module);
Wire.requestFrom(accel_module, 6);

int i = 0;
while(Wire.available()){
values[i] = Wire.read();
i++;
}
