### ⭐⭐⭐⭐⭐ Very useful and highly accurate!
*by S***. on January 14, 2020*

I added this to my WS1, put the WS1 in a watertight Pelican case, mounted as sensor externally, let it float on my pool and I have a wifi remote water temperature sensor! Well under 100$ total!

### ⭐⭐⭐⭐⭐ functions as described
*by J***N on December 17, 2019*

I deployed a test WS1 unit with this attachment and am VERY pleased!!! It is a must add-on accessory if the function is needed.

### ⭐ Not for direct USB usages.
*by A***A on November 9, 2025*

Despite using a USB plug, it does not use the USB protocol. Do not use this unless you have the product that this is supposed to come with. While the temp probe is supposed to be quite accurate, the probe itself is not expensive, and this is significantly more expensive than other DS18B20 probes. Find a different one, as you will likely have to cut off the port anyways. The highest quality part of this is the flat wire. Unless you need that, just use a cheaper version of this that already comes with useful ends.
