Public Lab Wiki documentation


The MACA Open Air Quality Monitor project (Monitor Abierto de Calidad del Aire in spanish) started a few years ago in Mendoza, Argentina to tackle some problems related to local air pollution monitoring (no public data, high costs of reference instruments, etc, etc) by developing an open, small and low cost air quality monitoring station.You can find more info about the MACA project in our wiki.

What are we doing?

Our first prototype was capable of measuring ozone and it worked ok as a proof of concept but we are currently working at Nodo39 Fablab on a second prototype that combines an optical particle detector (Shinyei) and metal oxide gas sensors for CO, NO2 and O3 (MICS-e2v). It's a remix and adaptation of previous citizen air quality monitors (AQ Egg, Smartcitizen, Dustduino and Airbeam). It is based on an Arduino Mega 2560.

Second prototype

This second version is still a work in process. We designed and assembled the first version and we are just starting to get data from the sensors.
