+description: |
+  Honeywell pressure sensor of model mprls0025pa.
+
+  This sensor has an I2C and SPI interface. Only the I2C interface is
+  implemented.
+
+  There are many models with different pressure ranges available. The vendor
+  calls them "mpr series". All of them have the identical programming model and
+  differ in the pressure range, unit and transfer function.
+
+  To support different models one need to specify the pressure range as well as
+  the transfer function. Pressure range needs to be converted from its unit to
+  pascal.
+
+  The transfer function defines the ranges of numerical values delivered by the
+  sensor. The minimal range value stands for the minimum pressure and the
+  maximum value also for the maximum pressure with linear relation inside the
+  range.
+
+  Specifications about the devices can be found at:
