Kernel driver aht10

Supported chips:

Author: Johannes Cornelis Draaijer <>


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 How to instantiate I2C devices for details.

Sysfs entries


Measured temperature in millidegrees Celcius


Measured humidity in %H


The minimum interval for polling the sensor, in milliseconds. Writable. Must be at least 2000.
