Sensirion — SEN6x Series Air Quality Sensing Platform

Sensirion SEN6x Indoor Air Quality Sensor

An industry-first sensing platform that measures up to nine environmental parameters including CO₂ and formaldehyde

The compact and powerful SEN6x sensing platform by Sensirion combines multiple sensors in a never-before-seen form factor and can measure up to nine environmental parameters (PM1, PM2.5, PM4, PM10, RH, T, VOC Index, NOx Index, CO₂ or HCHO). The innovative design simplifies integration, reduces costs, and allows for customization.

The SEN6x eliminates the complexities of sensor integration and development work, as it incorporates all the necessary algorithms. Customers can now focus on their core competencies and create user-friendly applications without the worry of costly and time-consuming optimizations, resulting in reduced time-to-market and cost of ownership.

Thanks to its modular approach, it offers flexibility and customization options. With just one design-in, customers can serve different product tiers, simplifying the production process and enabling tailored solutions for specific needs. Whether they require particulate matter measurements or a comprehensive range of air quality parameters, such as temperature, humidity, volatile organic compounds, nitrogen oxides, CO₂, or formaldehyde, the SEN6x provides the perfect combination.

At its core
At the core of the SEN6x is a brand-new, miniaturized, MEMS-based particulate matter sensing component – the SPS6x. It integrates all the necessary building blocks for measuring PM1, PM2.5, PM4, and PM10, revolutionizing air quality monitoring. The patented geometric arrangement, along with advanced MEMS and packaging techniques, allows for the integration of the light source, detector, signal processing, and algorithm into one cost- and space-efficient solution. The particulate matter sensing component is available as a part of the SEN6x.

The measurement of particulate matter relies on light scattering. When particles in the air pass through the beam of an integrated laser, they scatter the light, which is then captured by photodetectors. Onboard algorithms analyze the scattered light to determine the size distribution and mass concentration of the particles. With an integrated ASIC, no external processing is needed, and the SPS6x provides fully processed values through an I²C communication.

Upgrade your air quality monitoring with SEN6x and embrace simplicity, efficiency, and effectiveness.
