ADXL355 accelerometer code

I am doing a project which monitors vibrations using an ADXL355 sensor and an Arduino. I have used the MPU-9250 sensor before. I am not able to find a library or tutorials for calibrating, filtering, and reading accurate data from the sensor. Can…

How can I simulate an accelerometer?

I am new to Arduino. I want to simulate a circuit which uses an accelerometer ADXL335 and a DC motor. If any deviation observed in the accelerometer readings, I want the motor to rotate. Is there any way I can simulate its working in software…

What is corrrect the way to find roll, pitch, yaw?

I have an MPU9250. I have calculated accelerometer, gyroscope, magnetometer. But I want to know how to caclulate roll yaw pitch. I have searched on Google. I found many answer roll = (atan2(-Accel_Y, Accel_Z)*180.0)/M_PI; pitch = (atan2(Accel_X…

looking for a very accurate and sensitive accelerometer

For a research type project, we are looking for a very accurate and sensitive accelerometer (preferably 6-axis). The average range of the acceleration that we need to record is about 0.0003g (g=gravitational acceleration=9.81m/s2). The minimum…

Accelerometer readings on a moving object

I hope this stack is the right place for this question. I have an accelerometer mounted securely on a swaying object -lets say a stick or pole- this object is swinging back and forth in small angles (+- 20) with a frequency of about 2-3 times a…

Is it possible to measure the velocity of a Unmanned Aerial Vehicle using only accelerometer?

Our project is about dropping a payload from a UAV on the specified area. We are using an accelerometer (connected to the Arduino board) to measure the velocity of the plane (assuming the initial velocity to be zero). Is it possible to accurately…

Get the rotation on Genuino 101

How can I get the exact rotation of the Genuino 101? I would like to create a plumb rule. I tried the example app with processing, Arduino/Genuino 101 CurieIMU Orientation Visualiser, but it didn't get the correct rotation. Sometimes the object on…

Does anyone have code that successfully calculates velocity from an accelerometer

I'm trying to calculate the speed of a rocket for my project. I've been given the task of calculating this with an adxl3xxx accelerometer sensor. I'm not sure how to go about this as an accelerometer takes gravity acceleration into account. Can…
