|
|
|
The ``sps30`` sensor platform allows you to use your Sensirion SPS30
|
|
(`datasheet <https://sensirion.com/media/documents/8600FF88/616542B5/Sensirion_PM_Sensors_Datasheet_SPS30.pdf>`__) sensors with ESPHome.
|
|
The :ref:`I²C Bus <i2c>` is required to be set up in your configuration for this sensor to work.
|
|
This sensor supports both UART and I²C communication. However, at the moment only I²C communication is implemented.

|
Wiring:
|
|
-------
|
|
|
|
The sensor has a 5 pin JST ZHR type connector, with a 1.5mm pitch. (`Matching connector housing <https://octopart.com/zhr-5-jst-279203>`__, `datasheet <http://www.farnell.com/datasheets/1393424.pdf>`__)
|
|
To force the sensor into I²C mode, the SEL pin (Interface Select pin no.5) should be shorted to ground (pin no.4)
|

|
|
|
|
For better stability, the SDA and SCL lines require suitable pull-up resistors.
|
|
|
|
Automatic Cleaning:
|
|
-------------------
|
|
|
|
The SPS30 sensor has an automatic fan-cleaning which will accelerate the built-in fan to maximum speed for 10 seconds in order to blow out the dust accumulated inside the fan.
|
|
The default automatic-cleaning interval is 168 hours (1 week) of uninterrupted use. Switching off the sensor resets this time counter.
|
|
Disabling of automatic-cleaning or setting a manual interval is not supported at the moment.

.. _sps30_start_autoclean_fan_action:
|
|
|
|
``sps30.start_fan_autoclean`` Action
|
|
------------------------------------
|
|
|
|
This :ref:`action <config-action>` manually starts fan-cleaning.
|
|
|
|
