I've used several DS18B20 waterproof thermometers over the years and these are the best I've tried. Nice long cables (can be cut to any length of course) and they seem very well made. However, I get slight temperature fluctuations, which is to be expected. If I connect all 5 sensors to the same spot at the same time, I get the following readings: 72.2873.9671.9473.9672.50 This is normal for my project and may be within the specified error range, but note.
