Sensor node for all-in-one air quality sensing

28 July 2021 Test & Measurement

For applications like air purifiers, air conditioners, HVAC/ventilation systems and air quality monitors, Sensirion’s SEN55 environmental node is an all-in-one sensor solution for the accurate measurement of particulate matter, volatile organic compounds (VOCs), oxidising gases (NOx and O3) as well as humidity and temperature.

Thanks to proprietary algorithms, the module enables straightforward integration into customer applications. This allows device manufacturers to save valuable project time as well as personnel resources and to focus on their core competencies. End customers receive reliable air quality measurement data based on the SEN55 and benefit from improved air quality to increase health and comfort.
