Review on 10Pcs XINGYHENG Digital Temperature Sensors: Accurate Temp Probes by Derek Dolla

$2 each, I think that's a great price. Last time I bought a DS18B20 out of 10 I only received bare chips and paid about $1.50 each. So the inclusion of the assembly in a complete waterproof package is outstanding value to me. Of course I can find cheaper assembled units from China but not having to wait long for delivery is real value too. The blocks came with no documentation so there was no color code key but it's almost obvious. .red= VDDBlack= groundYellow= DQ
