Temperature Sensor STS3x
Best-In-Class Temperature Sensor For Various Applications
The STS3x is Sensirion’s newest 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, and improved accuracy specifications.
The functionality of Sensirion’s new 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 2.4 to 5.5 V and low current consumption (2 µA 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 +/–0.3°C (typical). There are two versions available: the standard version, STS31, guarantees an accuracy of ±0.3°C over a temperature range of –40°C to 90°C, while the low-cost version, STS30, has an accuracy range of 0°C to 65°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. An automotive version of the STS3x temperature sensor is also available.
