The sensor measures fine airborne particulate matter with a diameter of 2.5 microns (PM 2.5) or less. <span style='box-sizing: border-box; font-weight: bolder;'>PLEASE NOTE: We are currently experiencing technical issues with our air quality monitoring sensor. Repair efforts are under way, but reported values may not be accurate until full function is restored.</span></p><p style='box-sizing: border-box; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif; margin-top: 0px; color: rgb(85, 85, 85); font-size: 14px;'>In addition to PM 2.5 measurements, this dataset includes readings for pressure, temperature and humidity. Because the PurpleAir sensor is designed primarily for measuring airborne particulate matter and not for ideal temperature sensing, temperature values are provided as is and are just for interest.</p><p style='box-sizing: border-box; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif; margin-top: 0px; color: rgb(85, 85, 85); font-size: 14px;'>For more information on the PurpleAir Dual Laser Air Quality Sensor, visit: <a href='https://www.purpleair.com/' rel='nofollow ugc' style='font-family: &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 15px;' target='_blank'>https://www.purpleair.com/</a></p><p style='box-sizing: border-box; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif; margin-top: 0px; color: rgb(85, 85, 85); font-size: 14px;'>For general information on airborne particulate matter and interpreting PM 2.5 readings, visit: <a href='https://www.epa.gov/pm-pollution/particulate-matter-pm-basics' rel='nofollow ugc' style='font-family: &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 15px;' target='_blank'>https://www.epa.gov/pm-pollution/particulate-matter-pm-basics</a></p><p style='box-sizing: border-box; font-family: -apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif; margin-top: 0px; color: rgb(85, 85, 85); font-size: 14px;'><br /></p>
