Honeywell pressure sensor of model mprls0025pa.
This sensor has an I2C and SPI interface. Only the I2C interface is
implemented.
This sensor has an I2C and SPI interface.
There are many models with different pressure ranges available. The vendor
calls them "mpr series". All of them have the identical programming model and
