The AHT10/AHT20 is a Temperature and Humidity sensor
The address of this i2c device may only be 0x38
AHT20, DHT20 has additional CRC8 support which is sent as the last byte of the sensor values.
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.
