Sensirion has introduced the Environmental Sensor Node SEN6x which revolutionizes indoor air quality (IAQ) monitoring. SEN6x integrates all the essential sensors into one compact module, eliminating the complexities of integrating multiple sensors and dealing with complex optimizations which saves time, resources, and potential delays by providing an all-in-one design and pre-integrated algorithms.

SEN6x enables the measurement of up to nine environmental parameters, including PM1, PM2.5, PM4, PM10, RH, T, VOC Index, NOx Index, CO2, or HCHO. The design simplifies integration, reduces costs, and provides customization options, allowing users to tailor their monitoring solution to their unique requirements.

SEN6x incorporates all necessary algorithms, streamlining sensor integration and development, reducing time-to-market, and promoting cost savings. It enables the easy creation of user-friendly applications, eliminating complexities and accelerating IAQ monitoring solutions' deployment.
