Sensirion presents its fourth-generation temperature sensor series: the STS4x. The fully digital and cost-efficient temperature sensor is highly accurate and offers industry-leading lead times. The sensor platform is available in different accuracy classes and is currently represented by the STS40.

Due to its small size, cost-efficiency, and low power consumption, the STS4x is well-suited for mass production and battery-driven designs. The digital I2C interface enables operation without external signal disturbance, while proven production processes guarantee the highest reliability in the field. It also benefits from the high-tech engineering of a wide range of sensor components thanks to Sensirion’s CMOSens technology. Currently, the series is represented by the STS40, which comes with a temperature accuracy of ΔT = ± 0.2°C.

With functionalities like enhanced signal processing, three distinctive I2C addresses and communication speeds of up to 1 MHz, all sensors in the STS4x series offer top performance. Moreover, thanks to its tiny footprint of only 1.5 × 1.5 × 0.5 mm3, the dual-flat no-leads (DFN) package can easily be integrated into various applications. Furthermore, 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 measured once per second allows the series to be implemented into battery-driven designs. Overall, the STS4x series offers cost efficiency while maintaining top performance among comparable sensors on the market.
