Sensirion’s STS32, STS33, SHT33, and SHT43 series of low-drift digital calibrated and ISO17025 certified sensors, combine ISO17025 certified temperature and highly accurate humidity sensing in a single package. They rely on the industry-proven CMOSens® technology, enabling increased computational power, reliability, and improved accuracy specifications compared to their predecessors. Their functionality includes enhanced signal processing, two distinctive and user-selectable I2C addresses, and communication speeds of up to 1 MHz. The DFN package has a footprint of 2.5 mm x 2.5 mm with a height of 0.9 mm. Every sensor can be identified by its unique serial number and is supplied with an ISO17025 accredited calibration certificate for temperature measurement. The calibration certificate comprises three temperatures, -30°C, +5°C, and +70°C. All sensor-specific ISO17025 can easily be accessed through an API or Web-Access from libellus.sensirion.com.
