title: Honeywell TruStability HSC and SSC pressure sensor series
|
|
|
|
description: |
|
|
support for Honeywell TruStability HSC and SSC digital pressure sensor
|
|
series.
|
|
|
|
These sensors have either an I2C, an SPI or an analog interface. Only the
|
|
digital versions are supported by this driver.
|
|
|
|
There are 118 models with different pressure ranges available in each family.
|
|
The vendor calls them "HSC series" and "SSC series". All of them have an
|
|
identical programming model but differ in pressure range, unit and transfer
|
|
function.
|
|
|
|
To support different models one needs to specify the pressure range as well
|
|
as the transfer function. Pressure range can either be provided via
|
|
pressure-triplet (directly extracted from the part number) or in case it's
|
|
a custom chip via numerical range limits converted to pascals.
|
|
|
|
The transfer function defines the ranges of raw conversion values delivered
|
|
by the sensor. pmin-pascal and pmax-pascal corespond to the minimum and
|
|
maximum pressure that can be measured.
|
|
|
|
Please note that in case of an SPI-based sensor, the clock signal should not
|
|
exceed 800kHz and the MOSI signal is not required.
|
|
|
