Automatically measuring and graphing Air Quality with an inexpensive device (Sharp GP2Y1010AU0F Optical Dust Sensor)

Check out my latest results with the\u00a0Grove Shinyei Model PPD42NS Dust Sensor<\/a>\u00a0and\u00a0Dylos laser particle Sensor<\/a>. They are much better sensors.<\/b><\/p>

    Background<\/h2>

    With allergies and asthma I’m interested in both the indoor and outdoor air quality. I heat with a\u00a0Quadrafire<\/a>\u00a0woodstove. It is suppose to be a clean stove. I was interested in the impact on both my inside air (ie. ash\/dust) and outside air (smoke). New York State\u00a0monitors the air quality<\/a>\u00a0at several locations around the State. Certified Allergy & Asthma Consultants in Albany NY published daily pollen counts. The American Lung Association has a great article called\u00a0State of the AIR<\/a>\u00a0that talks about Particle Pollution. I have several weatherstations collecting data (\u00a0KNYREXFO1 [barn roof]<\/a>,\u00a0KNYCLIFT1 [garage roof]<\/a>\u00a0),<\/p>

    There are several citizen group projects that are developing open source equipment (e.g.\u00a0Air Quality Egg<\/a>). There are several\u00a0recent discussions about adding a Particulate sensor<\/a>. The Egg Project aims to give citizens a way to participate in the conversation about air quality. It is composed of a sensing device that measures the air quality in the immediate environment and an on-line community that is sharing this information in real-time. It is a community-developed, open source project that is driven by people who care about the air they breathe.<\/p>

    Monitoring<\/h2>

    The $290\u00a0Dylos Laser Particle Counter (DC1100) – with Computer Interface<\/a>\"\"\u00a0is a true Laser Particle Counter with two different size ranges. The small channel (0.5> Micron) should see bacteria and mold. The Large channel (2.5> micron) should see dust and pollen. The LCD display constantly shows bargraphs and values for the small and large particles. The unit saves 30 days of air quality data. I ordered the unit with the PC Interface Option and connected it to an Arduino Ethernet so I can automatically log the data to Pachube. That way air quality alerts can be triggered and sent to twitter and my cell phone.<\/p>
