SEN66
Upcoming Available Q2 2025Sensing platform for PM, RH/T, VOC, Nox and CO2 measurements
<p>Experience the future of air quality sensing with the compact and powerful SEN66. It combines multiple sensors in a never-before-seen form factor and can measure up to nine environmental parameters (PM1, PM2.5, PM4, PM10, T, RH, VOC Index, NOx Index, CO2). The innovative design simplifies integration, reduces costs, and allows for customization. At the core of the SEN66 is a brand-new, miniaturized, MEMS-based particulate matter sensing component – the SPS6x.</p><p> </p><p>Applications requiring compliance with IAQ standards – such as RESET®, WELL Building Standard™ and California Title 24 Building Energy Efficiency Standards – are well served by the SEN66.</p><p> </p><p>Learn more about the SEN6x series <a href="https://sensirion.com/sen6x-air-quality-sensor-platform"><strong><u>here</u></strong></a>.</p>
