Last time I checked thermistors also were analog. Of course the subject of the video is to advertise their semiconductor based analog temperature sensors, but they completely forgot about stability, aging, and noise of those. Everything depends on the application, and there are linear thermistors available as well. The most stable temperature sensors are platinum and ceramic NTC thermistors, and of course an experienced designer would never build a circuit like that. Our metrology grade thermistor instruments are capable of less than 100 micro-degrees peak to peak readout noise, with annual aging in the order of milli-degrees - you just can't get that with any semiconductor based temperature sensor. And what about the maximum temperature? Semiconductors only survive relatively low temperatures compared to other sensors.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
