 SHT21

The SHT21, a humidity and temperature sensor from Sensirion has achieved the AEC-Q100 automotive standard. This sensor has been in regular production since April 2010.

During the qualification process, the SHT21 was put through the relevant series of tests. Its ageing 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). Furthermore, 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.

The SHT21 humidity sensor confirmed its reliability, stability and robustness by passing all the tests without any permanent changes to its characteristics.
