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.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
