Sensirion SEN54-SDN-T Environment Sensor for PM, VOC, NOx, RH & T

Sensirion SEN54-SDN-T Environment Sensor for Particulate Matter, VOC, Relative Humidity, Temperature

The SEN54-SDN-T is a unique sensor module family combining the measurement of critical air quality parameters – particulate matter, VOC, NOx, humidity, and temperature – in a single package. The modules are a result of Sensirion’s extensive experience in environmental sensing and offers best possible performance of each sensing parameter, a superior lifetime, as well as a compact form factor.

The SEN54-SDN-T sensors provide fully calibrated outputs with a digital interface. The combination of all measurement parameters in a single device allows manufacturers of air quality devices to reduce design and integration efforts, shorten development times and simplify their supply chain. Proprietary algorithms enable straightforward integration into HVAC and air quality applications allowing resource/time savings and focus on core competencies. The implemented Sensirion Temperature Acceleration Routine (STAR) engine accelerates the device’s response to ambient temperature change by a factor of 2-3 to provide better UX and more accurate measurements to end users.
