Re: [Owfs-developers] New faulty DS18B20 - Solved it
It was all very simple. I was connecting the sensors via breadboard type connectors. My old one worked, the new ones didn't. I just tried connecting via the screw terminals on a Sheepwalk RPi2 and they all work fine. I guess the pins on the new ones must be a bit corroded and that stopped it making a good connection. Thanks for your help, sorry it was a bum steer. Mick On 04/08/2019 11:16, Jan Kandziora wrote: Am 04.08.19 um 10:02 schrieb Mick Sulley: Yes it does.

Mick, I made very good experience with https://www.fuchs-shop.com/ All sensors and other one wire components did work at arrival :-) Martin On 03.08.19 22:57, Mick Sulley wrote: > I recently bought 4 DS18B20 sensors from eBay.

Re: [Owfs-developers] New faulty DS18B20
Yes it does. I also have a DS18S20 inside the test box that I use, that shows as well. I have just tried a different DS2401 and get the same results.

Has anyone else bought sensors which do not work? Can anyone recommend a supplier whose sensors do work? Does the DS2401 iButton inside the DS9490 adapter show up? Chances are you blew up the DS9403 protection diode or the EMI choke in the GND line.
