Sensirion Offers Ultra-Low-Power Temperature Sensor

Sensirion presents its fourth-generation temperature sensor series: the STS4x. The digital sensor is highly accurate and offers industry-leading lead times. It 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. 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, due 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.

“Thanks to our many years of temperature sensing expertise, we were able to develop our tiniest temperature sensor to date, which despite its size and cost-efficiency offers top performance, outstanding accuracy and industry-leading lead times,” said Matthias Scharfe, product manager humidity and temperature sensors at Sensirion.
