Strictly speaking it is not the fifth birthday of Mars Rover Curiosity, since it had been built over many years and its journey from Earth to Mars took months but it was five (Earth) years ago that Curiosity landed on Mars for a 90 day mission. And it is still trundling around. Just shows that you can build reliable embedded systems.
 Why long-term consistent performance matters for relative humidity sensorsSponsored by Texas Instruments The open cavity sensing element included in relative humidity sensors is constantly exposed to the environment, leading to drift over time. The new relative humidity sensor, the HDC3020, offers integrated drift correction technology to reduce drift caused by environmental stress or interactions with contaminants. This article discusses the accuracy and long-term drift of humidity sensors and how these parameters impact end-equipment performance and lifetimes. |
