Can I use my phone as an accelerometer?

Acceleration can be measured with a small electronic device called an accelerometer. Most smartphones these days contain built-in accelerometers and can run apps that display the accelerometer readings.

What data does an accelerometer measure?

An accelerometer is a device that measures the vibration, or acceleration of motion of a structure. The force caused by vibration or a change in motion (acceleration) causes the mass to "squeeze" the piezoelectric material which produces an electrical charge that is proportional to the force exerted upon it.

How does an accelerometer collect data?

Accelerometers are wearable devices that measure accelerations of the body segment to which the monitor is attached. The signal is usually filtered and pre-processed by the monitor to obtain activity counts, i.e., accelerations due to body movement.

Can an accelerometer measure force?

What is an accelerometer? An accelerometer is an electromechanical device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or they could be dynamic - caused by moving or vibrating the accelerometer.
