Particle, VOC, Humidity, and Temperature Sensor – SEN54

The SEN54 sensor module from Sensirion combines the measurement of particulate matter, VOC, humidity, and temperature in a single package. The SEN54 sensors provide fully calibrated outputs with a digital interface, a strong lifetime under 24 h/day operation, and a compact form factor. The combination of all measurement parameters in a single device allows users to reduce design and integration efforts, shorten development times and simplify supply chain. Additionally, the included 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.
