The Weatherduino - Air Quality Monitor its a very simple to build device, suited to measure PM2.5 and PM10 air dust particles.\\ | |
Based on the PM2.5 readings, and in accordance with EPA standards the Air Quality Index is computed by using [[https://en.wikipedia.org/wiki/NowCast_(air_quality_index)|Nowcast]] functions implemented on the software.\\ | |
Currently, two models of dust particles sensors are supported: | |

Through the use of an optional [[http://www.winsen-sensor.com/d/files/infrared-gas-sensor/mh-z19b-co2-ver1_0.pdf|MH-Z19]] sensor, the Air Quality Monitor can also be used to monitor CO2 levels in a room, greenhouse or outside.<sup>3)</sup>\\ | Through the use of an optional [[http://www.winsen-sensor.com/d/files/infrared-gas-sensor/mh-z19b-co2-ver1_0.pdf|MH-Z19]] sensor, the Air Quality Monitor can also be used to monitor CO<sub>2</sub> levels in a room, greenhouse or outside.<sup>3)</sup> \\ The AQM (Air Quality Monitor) device can work in two different modes, simultaneously: |

* Work like a transmitter unit, providing WeatherDuino weather stations<sup>2)</sup> with Air Quality data, which by turn can be uploaded to WU, Thingspeak or even to your own server for SQL storage. | * First, as a transmitter to a WeatherDuino weather station<sup>2)</sup> with Air Quality data, which can, in turn, be uploaded to WU, [[http://www.meteocercal.info/forum/Thread-Air-Quality-Monitor-How-to-upload-data-to-ThingSpeak|ThingSpeak]] or even to your own server for storage in a SQL database. |
* Work as an independent device, that could be used by anyone, no matter have or not an WeatherDuino weather station. | * Second, as an independent device that could be used by anyone, whether they have a WeatherDuino weather station or not. |

| * Get the Part List from here: [[http://www.meteocercal.info/forum/Forum-WeatherDuino-Pro2-Pro2-PLUS-PCB-and-Parts-lists|WeatherDuino Pro2 & Pro2 PLUS - PCB and Parts lists]]\\ |
| * Always buy the PMS7003 sensor with the adapter cable included. |
| * There are two versions of the MH-Z19 sensor, preferably choose the MH-Z19B version. |
| |
| The Air Quality Monitor should be installed in a well-ventilated area outside the house, not exposed directly to elements such as rain, or direct sunlight.\\ |
| A porch or a balcony is a good place to install it.\\ |
| Choose an enclosure suitable for the environmental conditions where the AQM will be installed. If exposed to rain, the enclosure should be waterproof but allow air circulation.\\ |
