±0.2°C Ultra-low-power temperature sensor
The STS4x is Sensirion’s state-of-the-art, highly accurate digital temperature sensor series, boasting industry-leading lead times. It is a fully digital, highly cost-efficient temperature sensor platform that is available in different accuracy classes, currently represented by the STS40. The STS4x temperature sensor range features enhanced signal processing, three distinctive I²C addresses and communication speeds of up to 1 MHz. Moreover, the dual-flat no-leads (DFN) package has a footprint of only 1.5 × 1.5 mm² while retaining a height of 0.5 mm, which allows for an easy integration of the STS4x series into various applications. Additionally, the wide supply voltage range of 1.08 to 3.6 V and low current consumption of 0.4 µA for a typical average current at 1 measurement per second enables battery-driven designs. Taken together, the STS4x series achieves the greatest cost efficiency among comparable sensors on the market. Thanks to Sensirion’s CMOSens® Technology, the STS4x temperature sensor benefits from the high-tech engineering of a wide range of sensor components. It 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.
