Serial Particulate Matter
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
The configuration.yaml file is the main configuration file for Home Assistant. It lists the integrations to be loaded and their specific configurations. In some cases, the configuration needs to be edited manually directly in the configuration.yaml file. Most integrations can be configured in the UI. [Learn more] file:
