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](https://www.open-homeautomation.com/2016/07/19/measuring-air-quality/).

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](https://www.open-homeautomation.com/2016/07/20/connecting-an-particulate-matter-sensor-to-your-pc-or-mac/).

|
brand: oneair,s3
|
|
```
|
|
|
|
{% configuration %}
|
|
serial_device:
|
|
