The ``pm1006`` sensor platform allows you to use Cubic PM1006 particulate matter sensors (`datasheet <http://www.jdscompany.co.kr/download.asp?gubun=07&filename=PM1006_LED_PARTICLE_SENSOR_MODULE_SPECIFICATIONS.pdf>`__)
|
|
with ESPHome.

IKEA VINDRIKTNING Particulate Matter Sensor with PM1006 inside
|
|
|
|
As the communication with the PM1006 is done using UART, you need to have an :ref:`UART bus <uart>` in your configuration with the ``rx_pin`` connected to the TX pin of the
|
|
PM1006.
|
|
This component is currently RX-only, as the IKEA VINDRIKTNING already sends commands to the PM1006.
|
|
Additionally, you need to set the baud rate to 9600.

# Example configuration entry
|
|
uart:
|
|
rx_pin: D2
|
|
baud_rate: 9600
|
|
|
|
sensor:
|
|
- platform: pm1006
|
|
pm_2_5:
|
|
name: "Particulate Matter 2.5µm Concentration"
|
|
|
|
Unlike some other sensors, there is no configurable update interval, as this is a 'passive' implementation that picks up whatever the VINDRIKTNING MCU has requested from the sensor.
|
|
|
|
The implementation was inspired by https://github.com/Hypfer/esp8266-vindriktning-particle-sensor; you can also see the pinout there.
|
|
However, we recommend mounting your ESP below the fan (which blows out the front) so you do not obstruct the airflow.
|
|
`This discussion thread on the HA forum <https://community.home-assistant.io/t/ikea-vindriktning-air-quality-sensor/324599>`__ has several examples of how people have connected their ESP device to the IKEA sensor.

Configuration variables:
|
|
------------------------
|
|
|
|
- **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>`.
|
|
|
|
- **uart_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the :ref:`UART Component <uart>` if you want
|
|
to use multiple UART buses.
