Ds1820030598 1727read scratchpad behthis command reads the contents of the scratchpad. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin, no analog input pins needed. They are ds1820 not ds18b20 is there a significant difference.
This data sheet provides information on subminiature size, axial lead mounted. Ds1820 and ds18s20 temp probes whats the difference. If not all locations are to be read, the master mayissue a reset to terminate reading at any time. The biggest difference might be the difference in time for how long each device requires to take the temperature, so i suppose its possible that difference could cause a problem if you dont give it enough time to make the conversion. In order to meet the vih spec of the ds18s20, the actual supply rail for the strong pullup transistor must include margin for the voltage drop across the transistor.
