Accelerometer range meaning

Measurement Range: The level of acceleration supported by the sensor's output signal specifications, typically specified in ±g. This is the greatest amount of acceleration the part can measure and accurately represent as an output. For example, the output of a ±3g accelerometer is linear with acceleration up to ±3g.

What is accelerometer range?

Range. Most accelerometers will have a selectable range of forces they can measure. These ranges can vary from ±1g up to ±250g. Typically, the smaller the range, the more sensitive the readings will be from the accelerometer.

What do accelerometer values mean?

The accelerometer measures acceleration: In physics, acceleration is the rate of change of velocity over time. In one dimension, acceleration is the rate at which something speeds up or slows down. Positive values indicate an increase in velocity. Negative values indicate an decrease in velocity.

What is dynamic range of accelerometer?

The dynamic range of most accelerometers/ force transducers is 80 dB or more, considerably greater than other instrumentation in the measurement chain. When you need to measure abnormally low or high acceleration/force levels, you must consider the range of the sensor.

What does XYZ mean in accelerometer?

The X axis is parallel with the device's screen, aligned with the top and bottom edges, in the left-right direction. The Y axis is parallel with the device's screen, aligned with the left and right edges, in the top-bottom direction. The Z axis is perpendicular to the device's screen, pointing up.
