Overview

The STS33-DIS-2.5kS is a high-precision digital temperature sensor from Sensirion that features ISO 17025 certified calibration. Each sensor is NIST-traceable and comes with a 3-point calibration certificate, making it suitable for applications requiring documented accuracy and reliability. It operates over a wide voltage range of 2.15V to 5.5V and communicates via a standard I2C interface with a programmable ALERT pin.

Why Choose This Part

The STS33 offers industry-leading precision with a typical accuracy of +/-0.48 degrees Celsius and a resolution of 0.01 degrees Celsius. It is specifically designed for low-power operation, consuming only 0.2 uA in sleep mode, and features an integrated CRC checksum for reliable data communication. The inclusion of a sensor-specific calibration certificate simplifies compliance for engineers working in regulated industries.

Applications

Cold Chain Monitoring
Ensuring temperature-sensitive goods remain within required limits during transport with certified accuracy.
Medical Thermometry
High-precision body or fluid temperature measurement where ISO 17025 certification is required for regulatory compliance.
Industrial Process Control
Monitoring equipment and environment temperatures with high resolution and long-term stability in harsh industrial settings.
Environmental Monitoring
Precise climate tracking in data centers and laboratories where low drift and NIST traceability are critical.

Getting Started

Engineers can interface with the STS33 using the I2C Fast Mode protocol on any standard microcontroller. For rapid prototyping, use the Sensirion SEK-SensorBridge along with the SEK-STS3x evaluation kit and the ControlCenter software to visualize data. When designing the PCB, ensure proper thermal isolation of the 8-VFDFN package from heat-generating components to maintain sensing accuracy.

Also Consider

SHT31-DIS-B Sensirion - An alternative if both humidity and temperature sensing are required in the same small DFN package.
TMP117 TITexas Instruments - Offers higher typical accuracy and is also NIST-traceable for high-precision medical and industrial applications.
