Description
|
|
|
|
-----------
|
|
|
|
|
|
|
|
The AHT10 is a Temperature and Humidity sensor
|
|
|
|
|
|
|
|
The address of this i2c device may only be 0x38
|
|
|
|
|
|
|
|
Usage Notes
|
|
|
|
-----------
|
|
|
|
|
|
|
|
This driver does not probe for AHT10 devices, as there is no reliable
|
|
|
|
way to determine if an i2c chip is or isn't an AHT10. The device has
|
|
|
|
to be instantiated explicitly with the address 0x38. See
|
|
|
|
Documentation/i2c/instantiating-devices.rst for details.
