This driver implements support for the Sensirion flow and differential- pressure sensors that use the SF04 and SF05 chips.
The device communicates with the I2C protocol. Sensors can have any I2C adress, depending on their configuration. See Documentation/i2c/instantiating-devices for methods to instantiate the device.
The following device names are supported by the probe function: sfxx: The driver will try to detect the sensor chip and will self configure according to the settings of the sensor. sf04, sdp6xx: The driver will expect the SF04 sensor chip and will self configure according to the settings of the sensor. sf05, sfm3500: The driver will expect the SF05 sensor chip and will self configure according to the settings of the sensor.
measured_value - value, either flow or differential pressure scale_factor - the scale factor used by the sensor offset - the offset used by the sensor unit - the flow or pressure unit of the measured value
