## Sensor Comparison Tables

[[!toc levels="6"]]
Note, some of the table entries below use interval notation (min,typ,Max)
Examples
> **(,5,10)** Typical = 5, Maximum = 10
> **(3,5)** minimum = 3, Maximum = 5
Noninterval values are typical.

Notes for the accelerometer table
The table has been roughly ordered by a dynamic range figure of merit, defined here as fullscale range divided by noise density.
The LIS2L02AQ3 and LIS344ALH have two different selectable full scale ranges.
Specifications for both ranges are given is adjacent rows.
Despite note 10 in the datasheet, the bandwidth of LIS2L02AQ3 appears to be unspecified.
Bandwidth has been estimated as (resonant freq.)/10.
Like the LIS2L02' the LIS3LV02DQ has two different selectable full scale ranges,
and therefore is given two rows in the table.
The LIS3LV02DQ gives a resolution figure of 1 milligee @ 40 Hz for the +/2 gee span.
By simple division by the square root, the noise figure is 158 μgee as given in the table.
The datasheet does not appear to give a noise density specification.
The ADXL330 and LIS344ALH are 3axis accelerometers, but the z axis specification is markedly different from the xy axes. Therefore the xy and z specs are split into two rows in the table.
The ADIS16xxx series are standalone acquisition systems on a chip. I don't think they meet the requirements of our project.
The ADXL278 comes in variants with differing maximum gee ranges. The available ranges are +/35, +/50, and +/70 gee. The +/70 gee range is only available on a single axis, the cross axis in this case is +/35 gee. All other ADXL278 models have symmetric sensitivities.
At least the ADXL278 series and the ADXL78 series have part codes that don't include their base numbers. For instance the +/35gee version of the ADXL278 has the part number AD22284. This braindeadness has been ignored in the table.

## Definitions
 Part
 Part Identifier
 Price
 Price in small quantities.
If only the volume price is known, the small quantity price is taken as twice the 1k price.
 Bandwidth
 Acc
3dB sensor small signal bandwidth in Hz. For sampled systems value quoted is 1/2 the sample rate.
 Vsup

Normal operating voltage range.
 Isup

Normally operating supply current.
 Nonlin

NonLinearity. Maximum deviation of the output from a best fit line, as a percent of full scale
 Axes

Axes are independent measurement directions. The xy axes are assumed to be in the mounting plane,
the z axis is perpendicular to the mounting plane.
 Temperature Range

Sensor operating temperature range
 GainTC

Temperature coefficient of the sensor gain factor.
 Pkg

Packaging (DIP, etc.) If ambiguous, generally choose the smallest package.
 Intfc

Interface. Analog (anlg) is typical. Some sensors use digital outputs.
 Size

Largest dimension of part measured in any direction.
 Height

Distance from mounting plane to top of part.
### Definitions For Accelerometers
 Range

Maximum acceleration that can be measured by the sensor without saturation,
in gees where 1 gee ≅ 9.8m/s^{2}
 Noise

White noise as an RMS value per squareroot Hz. Units of microgee per rootHz.
 OffsetTC

Temperature coefficient of the zero acceleration bias in milligee per degree Celsius
### Definitions For Rate Gyros
 Range

Maximum rotation rate that can be measured by the sensor without saturation.
For some types, the range can be extended with some loss in sensitivity.
 Noise

White noise as an RMS value per squareroot Hz. Units of millidegree per second per rootHz.
 OffsetTC

Temperature coefficient of the zero rotation bias in degrees per second per degree Celsius
### Definitions For Magnetic Sensors
### Definitions For Pressure Sensors
 Range

Maximum pressure range over which the sensor is guaranteed to be (fairly) linear.
For some types, the range can be extended with minor increase in nonlinearity.
 Resolution

Minimum resolvable pressure change. Noise floor, or 1 LSB, whichever is greater.
 (ΔP vs T)

Indicated Pressure change over Temperature range
Maximum deviation in output at constant pressure over full operating temperature range.
 (ΔP vs P)

Indicated Pressure change over Pressure range
Maximum deviation in output at constant temperature over full operating pressure range.
