Sensirion is proud to announce its new calibrated and ISO 17025-certified temperature, and humidity and temperature sensors. These sensors enable customers to achieve cost-efficient GDP-compliant supply chain monitoring of drugs, vaccines and perishable goods.
The STS32 and STS33 are Sensirion’s new high-accuracy ISO 17025-certified digital temperature sensors optimized for cold and frozen chain applications. Both 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 distinct and user-selectable I2C addresses and communication speeds of up to 1 MHz. The DFN package has a footprint of 2.5 x 2.5 mm2 while keeping a height of 0.9 mm. Every STS32 or STS33 is identified by its unique serial number and is supplied with an ISO 17025-accredited calibration certificate. The calibration certificate comprises three temperatures, -30°C, 5°C and 70°C. In addition to the certified temperature sensors, Sensirion is introducing the SHT33 humidity and temperature sensor as the new flagship of the certified sensor family. The SHT33 is based on the proven SHT3x series, offering highest accuracy and quality standards combined with ISO 17025-certified temperature sensing on one chip (more info).
