-The AQM (Air Quality Monitor) device can work in two different modes. Both modes can work 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.
