Particulate matter Sensor

Particulate matter sensors measure the amount of very small particles in the air. A short introduction how these sensors work can be found on Open Home Automation.

Cheap LED based sensors usually use a GPIO interface that is hard to attach to computers. However, there are a lot of laser LED based sensors on the market that use a serial interface and can be connected to your Home Assistant system easily with an USB to serial converter.

At this time, the following sensors are supported:

oneair,s3
novafitness,sds021
novafitness,sds011
plantower,pms1003
plantower,pms5003
plantower,pms7003
plantower,pms2003
plantower,pms3003

To use your PM sensor in your installation, add the following to your configuration.yaml file:

sensor:
  - platform: serial_pm
    serial_device: /dev/tty.SLAB_USBtoUART
    name: Nova
    brand: novafitness,sds011

serial_device (Required): The serial port to use. On *nix systems, it can often be identified by $ ls /dev/tty*
name (Optional): The name displayed in the frontend.
brand (Required): Manufacturer and type of the sensor.
