SEN55
Environmental sensor node for PM, RH/T, VOC, NOx measurements
The SEN5x environmental node is a straightforward, all-in-one sensor solution platform for the accurate measurement of various environmental parameters, such as particulate matter, volatile organic compounds (VOCs), oxidizing gases, such as nitrogen oxides (NOx), as well as humidity & temperature. Thanks to proprietary algorithms, the module enables straightforward integration into various applications. This allows device manufacturers to save valuable project time and personnel resources and focus on their core competencies. End customers receive reliable air quality measurement data based on the SEN5x and benefit from improved air quality to increase health and comfort. On top of that, the SEN55 is compliant with the relevant healthy building standards RESET® and WELL Building Standard™.
Please note: Cables are not included. If cables are needed, please have a look at the SEK-SEN5x Evaluation kit.
