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.
Specifications about the devices can be found at:
