30-03-2022 | Sensirion | Test & Measurement

Sensirion now offers its fourth-generation temperature sensor series – the STS4x. The fully digital and cost-efficient temperature sensor is extremely accurate and provides industry-leading lead times. The sensor platform is offered in different accuracy classes and is currently represented by the STS40.

With its small size, cost-efficiency and low power consumption, the device is ideal for mass production and battery-driven designs. The digital I2C interface facilitates operation without external signal disturbance, while established production processes ensure the highest reliability in the field. On top of that, it benefits from the high-tech engineering of a broad range of sensor components thanks to the company's CMOSens technology. Currently, the series includes the STS40, which comes with a temperature accuracy of ∆T = ± 0.2C.

With functionalities like enhanced signal processing, three distinctive I2C addresses and communication speeds of up to 1MHz, all sensors in the STS4x series provide top performance. Moreover, due to its tiny footprint of only 1.5mm x 1.5mm x 0.5mm3, the DFN package can easily be integrated into different applications. Furthermore, the wide supply voltage range of 1.08V to 3.6V and low current consumption of 0.4µA for a typical average current measured once per second enables the series to be implemented into battery-driven designs. Overall, the series provides cost efficiency while maintaining top performance among comparable sensors.

"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. We want to give our customers the opportunity to cost-efficiently produce high-quality devices without long waiting times," says Matthias Scharfe, product manager, Humidity and Temperature Sensors at Sensirion.
