IIO stands for the [https://www.kernel.org/doc/html/v4.12/driver-api/iio/index.html Industrial I/O] subsystem of the Linux Kernel.
It generally provides an interface to sensors like Accelerometers and Light sensors.

== NixOS ==

The services using the subsystem can be enabled using this configuration in configuration.nix:

<syntaxhighlight lang=nix>
{ config }:
{
hardware.sensor.iio.enable = true;
}
</syntaxhighlight>

This will enable [https://github.com/hadess/iio-sensor-proxy iio-sensor-proxy].

To test, <code>monitor-sensor</code> can be used, it will print out the current values of the sensors as they change, periodically. In the event nothing is detected after enabling, rebooting may help.

== Software notes ==

It is unverified, but Gnome should automatically make use of the data when enabled to handle the rotation and automatic brightness of the display.

== Hardware notes ==

=== Accelerometers ===

Sometimes, the accelerometers in different devices will be oriented in a way that it specific to that hardware, this is not a ''problem'', but it is an ''issue'' to be considered. The [https://github.com/hadess/iio-sensor-proxy#accelerometer-orientation Accelerometer orientation section] on the <code>iio-sensor-proxy</code> project page explains how to fix this properly for your device. The NixOS specific note is that instead of creating an <code>hwdb</code> file, you would add <code>services.udev.extraHwdb</code> to your configuration.nix file.

<syntaxhighlight lang=nix>
{ config }:
{
services.udev.extraHwdb = ''
sensor:modalias:acpi:INVN6500*:dmi:*svn*ASUSTeK*:*pn*TP300LA*
ACCEL_MOUNT_MATRIX=0, 1, 0; 1, 0, 0; 0, 0, 1
'';
}
</syntaxhighlight>
