🌡️ Waterproof Digital Thermal Probe 1M: ELENKER DS18B20 Temperature Sensor – Pack of 5pcs for Accurate Temperature Measurement Review

After a week of testing 3 were installed but one was found to be accidentally stuck at 185F. I replaced it with one of the spares and they have been working great for the past few weeks. Nothing bad can be said about her. Setup was easy. Pull a 4k7 ohm resistor across VCC for the yellow DATA wire (leakage configuration) and tie red and black to GND.

Product delivered quickly and as expected. The temperature sensors look well made and should serve my purpose well. I use one on a Fibaro ZWave contact sensor and it immediately recognized and configured itself when I paired it with a SmartThings hub. It will eventually find use as a freezer temp monitor in our basement.

Tried this set of 5 because of the price and found the quality surprisingly good. When I tested these 5 thermometers overnight, I found that they were all within a few tenths of a degree Fahrenheit of between 32 degrees Fahrenheit and 70 degrees Fahrenheit. Exactly for my needs and within the specified tolerance. Each of them had canned wire. The cable is flexible. The block looks like the picture. They work with 5VDC or 3.7VDC. I use these thermometers in Arduino IoT projects with Arduino…
