PMSX003 Particulate Matter Sensor

:description: Instructions for setting up PMSX003 Particulate matter sensors
:image: pmsx003.png
The ``pmsx003`` sensor platform allows you to use your PMS5003, PMS7003, ... particulate matter
(`datasheet <http://www.aqmd.gov/docs/default-source/aq-spec/resources-page/plantower-pms5003-manual_v2-3.pdf>`__)
sensors with ESPHome.
As the communication with the PMSX003 is done using UART, you need
to have an :ref:`UART bus <uart>` in your configuration with the ``rx_pin`` connected to the SEND/TX pin
(may also be called the RX pin, depending on the model) of the PMS. Additionally, you need to set the baud rate to 9600.
This platform supports three sensor types, which you need to specify using the ``type:`` configuration
value:
- ``PMSX003`` for generic PMS5003, PMS7003, ...; these sensors support ``pm_1_0``, ``pm_2_5`` and ``pm_10_0`` output.
- ``PMS5003T`` for PMS5003T. These support ``pm_2_5``, ``temperature`` and ``humidity``.
- ``PMS5003ST`` for PMS5003ST. These support ``pm_2_5``, ``temperature``, ``humidity`` and ``formaldehyde``.

# Example configuration entry
uart:
rx_pin: GPIO23
baud_rate: 9600
sensor:
- platform: pmsx003
type: PMSX003
pm_1_0:
name: "Particulate Matter <1.0µm Concentration"

Configuration variables:
------------------------
- **pm_1_0** (*Optional*): Use the concentration of particulates of size less than 1.0µm in µg per cubic meter.
All options from :ref:`Sensor <config-sensor>`.
- **pm_2_5** (*Optional*): Use the concentration of particulates of size less than 2.5µm in µg per cubic meter.
All options from :ref:`Sensor <config-sensor>`.
- **pm_10_0** (*Optional*): Use the concentration of particulates of size less than 10.0µm in µg per cubic meter.
All options from :ref:`Sensor <config-sensor>`.
- **temperature** (*Optional*): Use the temperature value in °C for the ``PMS5003T`` and ``PMS5003ST``.
All options from :ref:`Sensor <config-sensor>`.
- **humidity** (*Optional*): Use the humidity value in % for the ``PMS5003T`` and ``PMS5003ST``.
All options from :ref:`Sensor <config-sensor>`.
- **formaldehyde** (*Optional*): Use the formaldehyde (HCHO) concentration in µg per cubic meter for the ``PMS5003ST``.
All options from :ref:`Sensor <config-sensor>`.
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the :ref:`UART Component <uart>` if you want
to use multiple UART buses.
