Review on 10Pcs XINGYHENG Digital Temperature Sensors: Accurate Temp Probes by Anthony Arcos

Two of my favorite features are 1) pest control and 2) versatility of interfaces. You can put 3 of these on one I/O pin before you run into any weirdness. On a nano with far fewer I/O pins than larger boards, this is VERY useful. Note that it can take up to a second for them to poll each sensor. Physically they *feel* hard. They have good sheathing and you don't have to worry about cable damage from normal moving and mixing that prototypes are prone to. The easiest way to test them: a cup of cold water, a cup of hot water. Just keep showing the sensor readings on the serial monitor. I was surprised at how responsive they were and all 10 read within 2 degrees (F) of each other, most within 0.1 degrees. Very impressive. I will buy them again.
