# Ikea Vindriktning PM2.5 sensor

Hey, thanks for the config!

I would recommend a filter, as the sensor puts out a lot of values in short succession which isn't necessary.

sensor:
  - platform: pm1006
    pm_2_5:
      name: "PM2.5 Bedroom"
      filters:
        - sliding_window_moving_average:
            window_size: 10
            send_every: 10

Thanks, I was unaware you could filter the input this way in esphome! That's a great suggestion!

I think a median or quantile filter is better suited for this type of sensors. They get rid of the outliers. See the core sensor description on the ESPhome documentation.
