Digital Temperature Sensor

Sensirion, has launched its new high-accuracy Digital Temperature Sensor STS3x. This is based on the same chip as the SHT3x humidity sensors and comes in a tiny eight-pin DFN package measuring only 2.5 x 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 linearised, 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 optimise overall power consumption.
