DS18B20 does not work with extended wire

[wildbilly]

I have run into a problem with reading temperature for the DS18B20. The sensor works fine plugged directly into the EasyPic4, but I extended the cable to 3 feet and triple checked the connections and it does not work. Does anyone know of this problem?

Try a lower value pullup resistor. Something like 1.5k.

Thank you. It worked.
