Sensors combine temperature and humidity measurement
Sensirion’s STS32, STS33, and SHT33 series of low-drift digital calibrated and ISO17025 certified temperature sensors combine ISO17025 certified temperature and highly accurate humidity sensing in a single package.
The sensors are in stock at distributor Digi-Key.
They rely on the industry-proven CMOSens technology, enabling increased computational power, reliability, and improved accuracy specifications compared to their predecessors. 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.
Features:
- Low drift, <0.01°C per year
- Sensor-specific calibration certificate
- JEDEC JESD47 qualification
- True NIST-traceability
- I2C FM, CRC checksum, multiple I2C addr.
- Tiny 8-pin DFN package with ALERT pin
- VDD = 2.15 V to 5.5 V
