Sensor nodes for reliable air quality data

26 April 2022 Analogue, Mixed Signal, LSI

Mouser Electronics is now stocking the SEN5x environmental sensor nodes from Sensirion. Optimised with multiple sensing parameters, the SEN5x nodes enable designers to save valuable R&D, BOM and assembly costs by providing an all-in-one sensor solution that replaces multiple environmental sensors.

The Sensirion SEN5x environmental sensor nodes help improve end-customers’ health and comfort by accurately measuring and reporting the levels of relevant indoor pollutants in particulate matter, volatile organic compounds (VOCs), oxidising gases (NOx and O3), humidity and temperature in a variety of air quality applications.

The advanced sensors offer easy integration, fully calibrated outputs with a digital interface, and optimal measurement of vital air quality parameters in a single device versus multiple sensor components. The sensor nodes provide one driver for up to eight data signals and perform all operations and communications through an I2C interface.

The SEN5x nodes feature integrated, proprietary measurement algorithms, including VOC/NOx index calculation, humidity compensation and temperature compensation, which enable straightforward integration into HVAC and air quality applications. Along with the temperature compensation engine, the devices also incorporate a Sensirion Temperature Acceleration Routine (STAR) engine, which accelerates their response to ambient temperature changes by a factor of 2 to 3.

The sensor nodes offer a lifetime of over 10 years and are available in a compact 52,8 x 43,6 x 22,3 mm form factor. For evaluation and development, Mouser also stocks the SEK-SEN5x evaluation kit.
