New high-accuracy digital temperature sensor from proven stable

07-03-2016 | Sensirion | Test & Measurement

Latest from Sensirion is the STS3x, a new high-accuracy digital temperature
sensor based on the same chip as the SHT3x humidity sensors housed in a tiny
eight-pin DFN package measuring only 2.5mm × 2.5mm2 with a height of just
0.9mm.

The sensor's tiny size and the wide supply voltage range of 2.4V to 5.5V
allow for integration in a great variety of applications. The sensor
delivers outstanding performance and a remarkably high accuracy of +/–0.3C
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 1MHz. 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.
