The genuine DS18B20 is accurate to ±0.5°C.I find that will all sensors. I think most report accuracy +/- 2 degrees. I have a calibration factor built into the processing based on mercury thermometers and/or hand held temperature/humidity sensors.Check the values returned against each other - the last cheap ones I bought reported 3ºC difference when next to each other.
