Sensors
=======

The device's non-display input and sensing hardware: capacitive touch, the
fingerprint sensor, the magnetic hall-effect cover switch, the detachable
keyboard cover's connector, and the sensor/fingerprint HAL layer. The active
pen (EMR digitizer) is display-adjacent and documented in
:doc:`/display/wacom-pen` instead, since it shares the panel and the e-ink
static-disassembly method. The power and volume buttons are physical keys,
not sensors, and are documented in :doc:`/boot/keys`.

All devices are DT-bound in ``artifacts/dtbo_a/overlay_0.dts`` and built into
``artifacts/kernel`` (:doc:`/boot/dtbo`); none of them are loadable modules.
The power and volume buttons (``gpio_keys``, ``qcom,qpnp-power-on@800``) are
physical keys, not sensors — see :doc:`/boot/keys`.
