| 22 | Description |
| 23 | ----------- |
| 24 | |
| 25 | The AHT10 is a Temperature and Humidity sensor |
| 26 | |
| 27 | The address of this i2c device may only be 0x38 |
| 28 | |
| 29 | Usage Notes |
| 30 | ----------- |
| 31 | |
| 32 | This driver does not probe for AHT10 devices, as there is no reliable |
| 33 | way to determine if an i2c chip is or isn't an AHT10. The device has |
| 34 | to be instantiated explicitly with the address 0x38. See |
| 35 | Documentation/i2c/instantiating-devices.rst for details. |
