BOJACK DS18B20 1M Temperature Sensor Temperature Probe Stainless Steel Package Waterproof(Pack of 2 Pcs）

If you are planning to use it with ESP32 use GPIO13 There are very few pins that work with such temp sensors. I had tough time using other pins besides 13 and 14. Also old libraries has timing issues so I went a few versions back to test these probes. Workgin for me now

Returning. Both sensors throw H/W failure errors when connected to my Fibaro Implant, when other sensors I have do not. Also, temperature is not responding. Quick test, hold the sensor in my hand, but temperature does not go up. Amazon has added a high return rate warning since I purchased them.

There are half a dozen sellers for this item, selling exactly the same electrical product with various cable lengths and add-on doodads. This is one is quite indistinguishable from the rest...... except for one annoying point: The seller has mis-labeled the wires. Yellow is Data, not Vcc. That's half an hour of my life I'll never get back. So... 3 stars for being totally average, minus one for screwing up the one thing you really should have double-checked.

I sorted by price and bought the cheapest one since they're probably all from the same factory. I've only used one of the two, but I connected it to a FireBeetle 2 (ESP32) and got it working with ESPHome easily. Just sitting on my desk, it seems to measure the room temperature as accurately as any other sensors I have around.I'm going to be using in this in my hot tub in a floating wireless thermometer, and it looks like it's going to work great for that.
