The SEN55 is an all-in-one environmental sensor node that measures particulate matter (PM1.0, PM2.5, PM4, PM10), humidity, temperature, and gas concentrations (VOC and NOx). It utilizes Sensirion's CMOSens technology for high accuracy and long-term stability. The sensor communicates via I2C and includes an integrated fan for active sampling and dust resistance.
