Sensirion SEN5x Environmental Sensor Nodes

Sensirion SEN5x Environmental Sensor Nodes are all-in-one sensor solutions for the accurate measurement of particulate matter, volatile organic compounds (VOCs), humidity, or temperature. Proprietary algorithms enable straightforward integration into HVAC and air quality applications allowing resource/time savings and focus on core competencies. The SEN5x devices feature a 4.5V to 5.5V range, 63mA average current consumption at 5V, a long lifetime, high dust resistance thanks to sheath flow technology, and an I2C interface. On top of that, the SEN50 is compliant with the relevant healthy building standards RESET® and well building standard™. End customers receive reliable air quality measurement data and benefit from improved air quality to increase health and comfort.
