# Learn about thermal interfaces

The thermal architecture includes the `sysfs` interface, which reads the thermal zone configurations and applies cooling actions to the CPU. The user space clients use the `sysfs` interface to communicate with the cooling map interface.

For more information about `sysfs` interface, see [Linux Kernel Thermal sysfs API Documentation](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/driver-api/thermal/sysfs-api.rst?h=v6.6).

You can interact with the device through the following interfaces:
