Design</b> <p> Gaia's external mechanical enclosure is specially designed, with a vent cap, which protects the sensors from direct wind and rain. The enclosure is made of UV-proof ABS plastic. </p> <center> <img style='width:100%;max-width:800px;' src='/air/view/gaia/images/gaia-a12-vent-cap-05.jpg'> <br> GAIA A12 external mechanical design </center> <li> <b>Maintainability</b> <p> The GAIA station is very easy to be maintained - specifically, changing the internal sensor can be done by anyone - you just need a standard screwdriver. </p> <center> <img style='width:100%;max-width:800px;' src='/air/view/gaia/images/gaia-a12-internal-02.jpg'> <br> GAIA A12 internal design: </center> <li> <b>Reliability</b> <p> Gaia uses 3 redundant dust sensors: The reason for using 3 redundant sensors is that, when one sensor fails, it is possible to know which one. <br> For stations with only two sensors, when a sensor fails, it is not possible to know which sensor is reporting correct data vs incorrect data. </p> <li> <b>Life Cycle</b> <p> The GAIA station uses a 25% duty cycle for dust sensors (active 90 seconds every 6 minutes). This makes it possible to operate the GAIA station for several years without the need for maintenance. </p> <li> <b>Data Quality</b> <p> For each sample interval (1 minute), GAIA provides the minimum, maximum, standard deviation, average and median for for interval. All this information is needed to extract reliable information about the sensor data quality. </p> <li> <b>Cost Effective</b> <p> Gaia station costs $200, and for this price, you get a 2x5 meters waterproof power cable and a power supply. </p> </li> <br> <center> <p> GAIA A12 Items included for $200 USD: </p> <img src='/air/view/gaia/images/gaia-a12-package2.jpg' style='max-width:1000px;width:100%;'> </center> </div> <style type='text/css'>section {margin-top:20px;margin-bottom: 80px;}@media only screen and (max-width: 800px) { border-top: 1px solid #ccc;}@media only screen and (min-width: 800px) { section {padding-left: 20px;border-left: 3px solid #f8f8f8;}}</style><h2><p>Ordering and Inquiry</p></h2><section><link href='/jscripts/fomantic-ui-2.9.3/dist/semantic.min.css?_=20250116.195014&type=css' rel='stylesheet'/><script src='https://aqicn.org/air-cache/jquery-3.7.1.min.js?_=20250116.195014' type='text/javascript'></script><script src='/jscripts/fomantic-ui-2.9.3/dist/semantic.min.js?_=20250116.195014&type=script'></script><script> var rates={"AR":[1004.8282560340948,"ARS"],"AU":[1.5300399234157445,"AUD"],"AT":[0.9437804783273838,"EUR"],"BD":[120.27666203680944,"BDT"],"BE":[0.9437804783273838,"EUR"],"BO":[6.979968247711662,"BOB"],"BR":[5.793305863286726,"BRL"],"BN":[1.3405561730014774,"BND"],"BG":[1.8462007209725482,"BGN"],"KH":[4085.098232533078,"KHR"],"CM":[619.154124659982,"XAF"],"CA":[1.401024188247913,"CAD"],"CL":[975.2886367853674,"CLP"],"CO":[4388.083910295479,"COP"],"CG":[619.154124659982,"XAF"],"HR":[0.9437804783273838,"EUR"],"CZ":[23.911659950121727,"CZK"],"DK":[7.0404400380800105,"DKK"],"EC":[1.006323866845661,"USD"],"EE":[0.9437804783273838,"EUR"],"ET":[124.05024558793932,"ETB"],"FI":[0.9437804783273838,"EUR"],"FR":[0.9437804783273838,"EUR"],"DE":[0.9437804783273838,"EUR"],"GH":[16.45460217659127,"GHS"],"GR":[0.9437804783273838,"EUR"],"HK":[7.8249660547139515,"HKD"],"HU":[387.26244596694335,"HUF"],"IN":[84.93043717029471,"INR"],"ID":[15848.589616554562,"IDR"],"IE":[0.9437804783273838,"EUR"],"IT":[0.9437804783273838,"EUR"],"JP":[154.45856380282123,"JPY"],"LV":[0.9437804783273838,"EUR"],"LT":[0.9437804783273838,"EUR"],"LU":[0.9437804783273838,"EUR"],"MO":[8.059573837358007,"MOP"],"MY":[4.4414129991795805,"MYR"],"ML":[619.1889709228028,"XOF"],"MU":[47.05580930185327,"MUR"],"MX":[20.479891037510566,"MXN"],"MN":[3419.4874566641283,"MNT"],"MM":[3268.4996417952343,"MMK"],"NP":[135.85165042601432,"NPR"],"NL":[0.9437804783273838,"EUR"],"NZ":[1.6861808533111837,"NZD"],"NG":[1683.8508348533624,"NGN"],"NO":[11.095476859676186,"NOK"],"PK":[279.65220699049803,"PKR"],"PE":[3.7899137847463598,"PEN"],"PH":[59.0747149576222,"PHP"],"PL":[4.11732255804387,"PLN"],"PT":[0.9437804783273838,"EUR"],"RO":[4.696411159057899,"RON"],"RU":[96.60220998454956,"RUB"],"RW":[1372.7742308661127,"RWF"],"SA":[3.7799814389924427,"SAR"],"SG":[1.3414593709192368,"SGD"],"SK":[0.9437804783273838,"EUR"],"SI":[0.9437804783273838,"EUR"],"ZA":[18.042076804796103,"ZAR"],"KR":[1410.41265218778,"KRW"],"ES":[0.9437804783273838,"EUR"],"LK":[294.55605420595475,"LKR"],"SR":[35.334020841149474,"SRD"],"SE":[10.908451657407962,"SEK"],"CH":[0.8859069156158703,"CHF"],"TW":[32.594716878413806,"TWD"],"TZ":[2676.968579659689,"TZS"],"TH":[34.72842522162114,"THB"],"TG":[619.1889709228028,"XOF"],"UG":[3687.0243536543376,"UGX"],"AE":[3.6962162026384955,"AED"],"GB":[0.7816616428822191,"GBP"],"US":[1.006323866845661,"USD"],"UY":[42.0147087489397,"UYU"],"VE":[3645459.932765381,"VEF"],"VN":[25490.17556564909,"VND"]};</script> <p class='cost_info'> Fill in the form below to get a quotation including the shipment cost. </p> <p class='cost_info' id='cost_info_AU' style='display:none'> Fill in the form below to get a quotation.
