What data does accelerometer give?

What is an Accelerometer? Accelerometers are devices that measure acceleration, which is the rate of change of the velocity of an object. They measure in meters per second squared (m/s2) or in G-forces (g).

How sensitive is an accelerometer?

If typical accelerometer sensitivity is 100 mV/G and you measure a 10 G signal, you expect a 1000 mV or 1 V output. The exact sensitivity is determined from calibration and usually listed in the calibration certificate shipped with the sensor. Sensitivity is also frequency dependent.

What can you do with the accelerometer data?

It measures the rotation of the device on each of its own 3 axis. Great for making games. The accelerometer measures angular acceleration instead of linear. Basically, you can use it to determine the orientation of a device in 3 dimensions. Think about the 3 different ways an object can spin and you’ll realize what those x, y, and z numbers are.

What causes the accelerometer to measure acceleration when standing still?

Accelerometers measure acceleration, often caused by motion. But when they are standing still, the only acceleration the accelerometer senses is due to gravity pulling down on it.

What is the range of an accelerometer for rockets?

For example, to measure small vibrations on a tabletop, using a small-range accelerometer will provide more detailed data than using a 250g range (which is more suited for rockets). The ADXL362 Triple Axis Accelerometer can measure ±2g, ±4g, and ±8g.

How does the accelerometer measure angular acceleration?
