The STS3x is Sensirion’s high-accuracy digital temperature sensor series. The STS3x temperature sensor utilizes the industry-proven CMOSens® Technology and wins over users with its increased intelligence, reliability, NIST traceability and improved accuracy specifications. There are also automotive grade versions available.

Every single STS3x is calibrated and 100% end tested. The calibration is performed with a reference sensor which is NIST traceable through an ISO/IEC 17025 accredited laboratory.

The functionality of Sensirion’s STS3x temperature sensor includes enhanced signal processing, two distinctive and user-selectable I²C addresses, and communication speeds of up to 1 MHz. The dual-flat no-leads (DFN) package has a footprint of 2.5 × 2.5 mm² while retaining a height of 0.9 mm. This allows for easy integration of the STS3x series into various applications. Additionally, the wide supply voltage range of 2.15 to 5.5 V and low current consumption (1.7µA typical average current at 1 measurement per second) guarantees compatibility with a wide range of applications.

The STS3x temperature sensor gives a fully calibrated, linearized, and supply-voltage-compensated digital output and has an outstanding accuracy of up to +/–0.1°C. There are three versions available: the standard version, STS31, guarantees an accuracy of ±0.2°C over a temperature range of 0°C to 90°C, while the low-cost version, STS30, has an temperature range of 0°C to 65°C. The high-end version STS35 is the most accurate temperature sensor available with an accuracy of ±0.1°C over a temperature range of 20 to 60°C.

Thanks to Sensirion’s CMOSens® Technology, the STS3x temperature sensor is designed for mass production, comes with a high signal-to-noise ratio and high process capability, and is proven to be highly reliable and stable over the long term.
