Hi,
Have used NTCs as off board aqaurium \creature\plant temp sensors to micros and the DS18B20 seems to be a good digital alternative, but wonder if they are as reliable in terms of total failure?
Being a much more active device does the DS18B20 seem to be as long lasting as a ntc can be ?
Would be interested to hear other folk views; partic from any professional users as its noticable many commercial temp based devices still seem to use a ntc.
Also while a genuine Dallas 18B20 purchased from one of the major suppliers should be first quaility and give the best service life , many folk including myself , seem to buy the far east steel encapsuled types with ready made lead attached, so again wonder if they really contain a genuine 18B20 or possibly low spec devices ?
