Sensirion SEN66 Environmental Sensor Node

The SEN66 is a sensing platform for PM, RH/T, VOC, Nox and CO2 measurements. 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 customisation. At the core of the SEN66 is a brand-new, miniaturised, MEMS-based particulate matter sensing component – the SPS6x. 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. We stock an Adafruit SEN6x Breakout to allow you to easily use this sensor with a range of development boards. Features

* All-in-one environmental node: no co-integration of separate sensor components required

* Integrated temperature and humidity compensation and VOC/NOx index calculation

* Optimised and tested air flow channel geometry and proven design-in examples

* Patented sheath-flow technology combined with high-quality components Dust-protection and long lifetime

* Fast time-time-to-market, less R&D expenses, bill of material and assembly costs

* Reliable and trustworthy measurements

* Fast hardware design

* Dust-protection and long lifetime
