Hopefully there's been a terrible mistake somewhere! I'm just gearing up for a little project involving over 10 DS18B20 temperature sensors, but I'm struggling to find any sources. I started on the flea market and the big-forest-place and the bad reviews/reports of fakes put me off, so I moved on to the professional electronics suppliers. Most seem to be out of stock; then (shock horror) Digikey have them listed as 'obsolete'!
The manufacturer - Maxim - have the details in their parametric search, but all links to the page seem to be broken at the moment.
I of course remembered the PICAXE shop and came here; but I'm now concerned that the PICAXE store description says 'new die revision'. I'm aware there are plenty of variants of the DS18B20 - but there seems to be little information on which ones are directly compatible with our friendly ReadTemp12 command.
So, does anyone know which variants are safe to use? Are there any later alternatives? Can hippy/Technical reveal exactly which die revision is stocked in the store?
I'm actually worried about not using the so familiar DS18B20!!
Thanks.
