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. | |
