Particulate matter sensors measure the amount of very small particles in the air.
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 a USB to serial converter.
## Supported Sensors
At this time, the following sensors are supported:
- oneair,s3
- novafitness,sds021
- novafitness,sds011
- plantower,pms1003
- plantower,pms5003
- plantower,pms7003
- plantower,pms2003
- plantower,pms3003
## Configuration
To use your PM sensor in your installation, add the following to your `configuration.yaml` file:
```yaml
sensor:
- platform: serial_pm
serial_device: /dev/tty.SLAB_USBtoUART
brand: oneair,s3
```
{% configuration %}
serial_device:
description: The serial port to use. On *nix systems, it can often be identified by `$ ls /dev/tty*`
required: true
type: string
name:
description: The name displayed in the frontend.
required: false
type: string
brand:
description: Manufacturer and type of the sensor. (Use a value from the supported sensors list.).
required: true
type: string
{% endconfiguration %}
### Named Sensor Configuration Example
```yaml
sensor:
- platform: serial_pm
serial_device: /dev/tty.SLAB_USBtoUART
name: Nova
brand: novafitness,sds011
```
