Sensirion's new SHT21 humidity and
temperature sensor has been qualified in accordance with the AEC-Q100
automotive standard. During the qualification process, the SHT21 was put
through the relevant series of tests. Its aging resistance was confirmed by the
High Temperature Operating Lifetime (HTOL) test,
and its stress resistance was demonstrated by the Unbiased Highly Accelerated
Stress Test (UHST). A Temperature Cycling (TC) test confirmed the compatibility
of the packaging material with the chip and substrate, and the Electrostatic
Discharge (ESD) and Electromagnetic Compatibility (EMC) tests proved the
robustness of the sensor with regard to these parameters.
SHT21 humidity sensor passed all the tests without any permanent changes to its
characteristics and therefore fulfilled the quality requirements of the
AEC-Q100 automotive standard. This qualification, along with the reliability,
stability and robustness it certifies, allows users to employ the SHT21 with proper,
