# Receive sensor temperature notifications

The thermal core framework uses the `Netlink` interface to provide sensor temperature notifications to the user space.

The user space applications use the `Netlink` library API to get notifications of the sensor temperature and take required action. `Netlink` library APIs are available at: [index: kernel/git/torvalds/linux.git](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/lib/thermal?h=v6.6).
