:description: Instructions for setting up LD2410 sensors.
:image: ld2410.jpg
Component/Hub
-------------
.. _ld2410-component:
The ``ld2410`` sensor platform allows you to use HI-LINK LD2410 motion and presence sensor
(`datasheet and user manual <https://drive.google.com/drive/folders/1p4dhbEJA3YubyIjIIC7wwVsSo8x29Fq-?spm=a2g0o.detail.1000023.17.93465697yFwVxH>`__) with ESPHome.
The :ref:`UART <uart>` is required to be set up in your configuration for this sensor to work, ``parity`` and ``stop_bits`` **must be** respectively ``NONE`` and ``1``.
Use of hardware UART pins is highly recommended, in order to support the out-of-the-box 256000 baud rate of the LD2410 sensor.

id: my_ld2410
password: !lambda 'return password;'
OUT pin
-------
In order to monitor the presence indicated by the component, with the :ref:`light function<ld2410-light-function>` taken
under account, you can set up a :ref:`GPIO Binary Sensor <gpio-binary-sensor>`:

Calibration Process
-------------------
In order to calibrate your ``ld2410`` sensor perform the following:
1. Enable :ref:`engineering mode<ld2410-engineering-mode>`.
2. Monitor the ``gX_move_energy`` and ``gX_still_energy`` :ref:`sensors<ld2410-sensors>`.
3. Change the :ref:`thresholds<ld2410-number>` and repeat step 2 until satisfaction.
4. Disable :ref:`engineering mode<ld2410-engineering-mode>`.
