This is a new driver for the Honeywell Humidicon HIH-6130/HIH-6131 humidity sensor. The driver is based on the existing Sensiron sht21 driver with the necessary changes to the probe, update_measurements and conversion functions necessary to use the Honeywell sensors. There's no difference between the 6130 & 6131 other than the 6131 having an external condensation filter attached.

Description
|
|
-----------
|
|
|
|
The HIH-6130 & HIH-6131 are humidity and temperature sensors in a SO8 package.
|
|
The difference between the two devices is that the HIH-6131 has a condensation
|
|
filter.
|
|
|
|
The devices communicate with the I2C protocol. All sensors are set to the same
|
|
I2C address 0x27 by default, so an entry with I2C_BOARD_INFO("hih6130", 0x27)
|
|
can be used in the board setup code.
|
|
|
|
Please see Documentation/i2c/instantiating-devices for details on how to
|
|
instantiate I2C devices.
