Description
-----------
The AHT10/AHT20 is a Temperature and Humidity sensor
The address of this i2c device may only be
0x38
Special Features
----------------
AHT20 has additional CRC8 support which is sent as the last byte of the sensor
values.
Usage Notes
-----------
This driver does not probe for AHT10/ATH20 devices, as there is no reliable
way to determine if an i2c chip is or isn't an AHT10/AHT20. The device has
to be instantiated explicitly with the address
0x38. See
Documentation/i2c/instantiating-devices.rst for details.
Sysfs entries

=============== ============================================
temp1_input Measured temperature in millidegrees Celsius
humidity1_input Measured humidity in %H
update_interval The minimum interval for polling the sensor,
in milliseconds. Writable. Must be at
least
