Two arduino Uno with 4 MPU6050 MATLAB

Greetings,

I have connected two arduino uno with 4 mpu6050 IMUs and attached all of them to a body, i want to take accleration of the body if it moves, not when it is at rest. I donwnloaded Arduino support package for MATLAB, and tried different logic of code to take measurements from MPU6050 only when it moves, unfortunatley I get all the measurements while moving and at rest, please propose any modification to the code>>

Generating IMUs readings through Arduino UNO:

% Identifying Two Arduino Uno

Right = arduino('COM9', 'Uno', 'Libraries', 'I2C');

LEFT = arduino('COM10', 'Uno', 'Libraries', 'I2C');

% Declaring 4 MPU6050 IMUs

imu1= mpu6050(Right,'SampleRate',160,'SamplesPerRead',10,'I2CAddress','0x68','ReadMode','Latest');

imu2 = mpu6050(Right,'SampleRate',160,'SamplesPerRead',10,'I2CAddress','0x69','ReadMode','Latest');

imu3 = mpu6050(LEFT,'SampleRate',160,'SamplesPerRead',10,'I2CAddress','0x68','ReadMode','Latest');

imu4 = mpu6050(LEFT,'SampleRate',160,'SamplesPerRead',10,'I2CAddress','0x69','ReadMode','Latest');

% logging measurements

IMU1_mueasurements=zeros(100,3);

IMU2_mueasurements=zeros(100,3);

IMU3_mueasurements=zeros(100,3);

IMU4_mueasurements=zeros(100,3);

accelReadings1=zeros(100,3);

accelReadings2=zeros(100,3);

accelReadings3=zeros(100,3);

accelReadings4=zeros(100,3);

[accelReadings1(1,:)] = readAcceleration(imu1);

[accelReadings2(1,:)] = readAcceleration(imu2);

[accelReadings3(1,:)] = readAcceleration(imu3);

[accelReadings4(1,:)] = readAcceleration(imu4);

for R= 2:100

[accelReadings1(R,:)] = readAcceleration(imu1)

if (accelReadings1(R)-accelReadings1(R-1))>0.5

IMU1_mueasurements(R)=accelReadings1(R);

end

[accelReadings2(R,:)] = readAcceleration(imu2)

if (accelReadings2(R)-accelReadings2(R-1))>0.5

IMU2_mueasurements(R)=accelReadings2(R);

end

[accelReadings3(R,:)] = readAcceleration(imu3)

if (accelReadings3(R)-accelReadings3(R-1))>0.5

IMU3_mueasurements(R)=accelReadings3(R);

end

[accelReadings4(R,:)] = readAcceleration(imu4)

if (accelReadings4(R)-accelReadings4(R-1))>0.5

IMU4_mueasurements(R)=accelReadings4(R);

end
