name: "Particulate Matter 2.5µm Concentration"
update_interval: 20s
If you run the PM1006 (2.5µm) or PM1006K (1, 2.5, 10µm) independent from the original MCU you need to send a serial command in the first 5 seconds after power is applied to the sensor. Otherwise the sensor will switch to PWM mode and does not repond to UART requests. A possibility to do this in ESPhome is to use an automation. `Source <https://community.home-assistant.io/t/ikea-vindriktning-air-quality-sensor/324599/300>`_
