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