-<sup>1)</sup> The very expensive PurpleAir Air Quality Monitor, uses an Plantower sensor (the PMS5003older than PMS7003).\\ +The WeatherDuino Air Quality Monitor it very simple to buildand enables the user to measure PM2.5 and PM10 dust particles which are important measures of air pollution.\\ 
-<sup>2)</sup>  - See [[:weatherduino_receivers#weatherduino_receivers_-_comparison_chart|systems compatibility here]].\\ +Based on the PM2.5 readingsand 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 in the WeatherDuino software.\\ 
-<sup>3)</sup>  - Precision measure of CO2 concentration in open air, is very complicated task no achievable with simple equipmentAccording to specifications the error margin of an MH-Z19 sensor is - 50ppm for indoor usemaybe more in outdoor use.\\ +Currently, two models of dust particle sensors are supported: 
-<sup>4)</sup>  Must match the frequency used by other Transmitter units.+ 
 +  [[http://aqicn.org/sensor/pms5003-7003/|PMS7003]], from the well known brand [[http://www.plantower.com/en/content/?110.html|Plantower]].<sup>1)</sup> 
 +  * [[http://aqicn.org/sensor/sds011|Nova SDS011]] made by [[http://www.inovafitness.com/en/a/chanpinzhongxin/95.html|Inovafitness]]. 
 + 
 +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: 
 + 
 +  * 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. 
 +  * Second, as an independent device that could be used by anyone, whether they have a WeatherDuino weather station or not. 
 + 
 +In the Assembly Guide / Hints section below, we will explain how to set-up the AQM for each mode of use.

 +  * 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.\\
