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,

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
