What is a 3-axis accelerometer?

A 3-axis accelerometer is a sensor that measures acceleration in the X, Y, and Z directions. First, acceleration is Newton's law of motion (second law). ""When an object receives an external force F, it is proportional to the magnitude of the force F in the direction of that force, and becomes the mass m of the object. It produces an inversely proportional acceleration a. "" Expressed in a mathematical formula, it becomes ""F = ma"". To put it plainly, acceleration is "the amount of change in velocity over a period of time." Accelerometers can detect movements, vibrations, and impacts of objects by measuring acceleration and processing signals. Gravity can also be measured, and tilt can be detected by calculating gravity. There are three types of accelerometers, such as piezoelectric type, piezo resistance type, and capacitance type, which are selected according to the application.
