  3. Background on VOCs • Volatile Organic Compounds (VOCs) are “organic chemicals that have a high vapor pressure and easily form vapors at normal temperature and pressure” • VOCs can be carcinogenic, toxic, and flammable • They can originate from clothing, building materials, cars, trees (http://www.ilpi.com/msdS/ref/voc.html)

  4. Household VOCs • Formaldehyde • Can be found in adhesives for carpets, facial tissues and other hygienic products, and insulation • Carcinogenic • Benzene • Can be found in tobacco smoke, fuel, paint supplies, and car exhaust • Carcinogenic • Dichloromethane (methylene chloride) • Found in spray paints, adhesive removers, and some aerosols • Converted into carbon monoxide in the body

  5. Our Solution • A fan to detect the levels of VOC’s in common living space • Fans circulate air around the rooms where we spend our time • Our fan will alert you to what is actually in the air you are circulating • Color changing led's alert the consumer to changing levels of VOC’s • High levels of VOC’s are signaled by an auditory cough

  6. Prototype Design • Synkera 707 VOC sensor is added into bottom vent of the fan • VOC’s are heavier than air • LEDs along the back edge of the fan glow in color in accordance to VOC concentration • Range of color is from blue (no VOCs detected) through green, yellow, orange, and red (high concentration of VOCs)

  7. Prototype Design cont’d • The fan will make an audible “cough” when the red LED indicates a high concentration of VOCs • The VOC sensor, LEDs, and speaker for the “cough” will be powered by rechargeable batteries • Batteries are charged by docking them on a solar cell charger • Codename: “FANtastic”

  8. Speaker for “cough” Air exits through vent LEDs on back panel Synkera 707 VOC Sensor in air column Rechargeable batteries from solar cell charger Air enters through fans
