This Pmod is an easy way to add indoor air quality measurements to your FPGA or Arduino design!<\/p>\n\n\n\n<p>The <a href=\"https:\/\/digilent.com\/shop\/pmod-aqs-digital-gas-sensor-for-air-quality\/\">Pmod AQS<\/a> uses the CCS811 system on chip solution to provide readings of <strong>volatile\u00a0organic\u00a0compounds\u00a0(VOC)<\/strong> in I2C data format. This solution involves an integrated MOX (metal oxide) sensor which is read into a 10 bit ADC where the microcontroller is able to perform calculations on the raw sensor data, drive different modes and read out results. This microcontroller is relatively low-power consuming, allowing designers to preserve valuable battery life.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"800\" src=\"https:\/\/digilent.com\/blog\/wp-content\/uploads\/2019\/01\/2.png\" alt=\"\" class=\"wp-image-26383\" srcset=\"https:\/\/digilent.com\/blog\/wp-content\/uploads\/2019\/01\/2.png 800w, https:\/\/digilent.com\/blog\/wp-content\/uploads\/2019\/01\/2-150x150.png 150w, https:\/\/digilent.com\/blog\/wp-content\/uploads\/2019\/01\/2-600x600.png 600w, https:\/\/digilent.com\/blog\/wp-content\/uploads\/2019\/01\/2-768x768.png 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p>So, what exactly can you measure with a VOC sensor? <br><strong>VOC\u00a0<\/strong>measurements are primarily used to detect human-irritant compounds in the air.  Common items that emit detectable VOCs include: <\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>paints, paint strippers and other solvents<\/li><li>wood preservatives<\/li><li>most aerosol sprays<\/li><li>cleansers and disinfectants<\/li><li>moth repellents and air fresheners<\/li><li>stored fuels and automotive products<\/li><li>hobby supplies and craft glues<\/li><li>dry-cleaned clothing<\/li><li>pesticides<\/li><li>perfumes<\/li><li>building materials and furnishings<\/li><li>office equipment such as copiers and printers, correction fluids and carbonless copy paper<\/li><li>smokes (cigarette, marijuana and cigar etc.)<\/li><li>gaseous human emissions<\/li><\/ul>\n\n\n\n<p>Basically anything that has a potential detectable to the human nose, (&#8220;smell&#8221;), will most likely be able to be measured by the Pmod AQS. <\/p>\n\n\n\n<p>You can use the <a href=\"https:\/\/digilent.com\/shop\/pmod-aqs-digital-gas-sensor-for-air-quality\/\">Pmod AQS <\/a>to measure the overall contamination level of the air in a space for highly scientific and health related reasons&#8230; or you could create a <a href=\"https:\/\/people.ece.cornell.edu\/land\/courses\/ece4760\/FinalProjects\/s2009\/rac82_mos22\/rac82_mos22\/index.htm\">fart detector<\/a>. We know you were all thinking it. The answer is yes. Yes you can. <\/p>\n\n\n\n<p>And you should!
