The ``pmsx003`` sensor platform allows you to use your Plantower PMS5003, PMS7003, ... laser based particulate matter sensors
(`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.
2022-12-23 13:45:46 +01:00
- ``PMS5003S`` for PMS5003S. These support ``pm_1_0``, ``pm_2_5`` and ``pm_10_0`` and ``formaldehyde``.
- ``PMS5003T`` for PMS5003T. These support ``pm_1_0``, ``pm_2_5`` and ``pm_10_0``, ``temperature`` and ``humidity``.
- ``PMS5003ST`` for PMS5003ST. These support ``pm_2_5``, ``temperature``, ``humidity`` and ``formaldehyde``.
Sensor Longevity
------------------------
The laser diode inside the PMSX003 has a lifetime of about 8000 hours, nearly one year.
If you wish to use the optional ``update_interval`` ensure you have a ``tx_pin`` set in the UART configuration and connected to the RECEIVE/RX pin
(may also be called the TX pin, depending on the model) of the PMS. Setting ``update_interval`` to 120 seconds or higher may help extend the life span of the sensor.
