Sensirion launches New High-Accuracy Digital Temperature Sensor

Sensirion, the world's leading manufacturer of humidity and temperature sensors, is presenting its new high-accuracy digital temperature sensor STS3x. The new STS3x temperature sensor is based on the same chip as the SHT3x humidity sensors and comes in a tiny eight-pin DFN package measuring only 2.5 × 2.5 mm2 with a height of 0.9 mm.

Its tiny size and the wide supply voltage range of 2.4 V to 5.5 V allow for integration in a great variety of applications. The sensor delivers outstanding performance and a remarkably high accuracy of +/-0.3°C over an extensive temperature range combined with low power consumption - an especially important consideration for battery-operated devices.

The industry-proven CMOSens® technology is the basis of the STS3x sensor, offering increased intelligence, reliability, and improved accuracy compared to its predecessors. Furthermore, the sensor demonstrates a very fast start-up and response time, and its functionality includes enhanced signal processing, two distinctive and user selectable I2C addresses and communication speeds of up to 1 MHz.

The STS3x temperature sensor is calibrated to provide a linearized, digital output that is compensated for supply voltage instabilities. Qualification is based on JESD 47, with a dedicated automotive qualification plan certified according to AEC Q100. The alert option with definable temperature set points enables using the sensor as a watchdog and can thus strongly optimize overall power consumption.

The STS3x sensor is ideal for demanding data logger and temperature compensation applications. Due to its high accuracy, body temperature measurement in wearable devices and temperature calibration in automotive components are among the main target applications. In addition, a multitude of HVAC devices will benefit in terms of precision, power savings, and reliability when accounting for highly accurate temperature data.

All in all, STS3x temperature sensors fulfill the most stringent requirements for many applications in terms of quality, performance, and cost-effectiveness, derived from Sensirion's unique digital-sensor expertise of more than 15 years.
