1  Using Arduino / Sensors / DS18b20 and onewire - output problems on: February 17, 2011, 11:59:51 am
Im using Duemlanove with Drobot 1820b sensors with 4k7 resistor and Miles Dallas temperature library. Using his 'simple' sketch the response is -72C which ouputs constantly. using 'single' sketch output is 0C 32F. these outputs are constant regardless of heat applied to the DS18b20, this suggested prob could be sensor, but ive tried 3 now to no avail !!  Ive also tried parasitic & powered modes which give same results. Using sheepdog software (no onewire lib) I again got constants which didnt change. any guidance gratefully received
