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,

Design engineer compensation varies widely by location. If you live in Boston, your salary will average more than $90,000, nearly $20,000 above the national average. But if you live in Cleveland, your salary will average almost $10,000 below the national average.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
For many years, it was believed that the strongest biological substance on Earth was spider silk, but new research says aquatic snails produce an even stronger material that could disrupt manufacturing forever.
Most everyone thinks they are ready for an emergency or a disaster. Most everyone is wrong. But engineers are a unique position here as both the designers and beneficiaries of emergency preparedness systems.
