DS18B20 Temperature Probe, Waterproof External Probe for Refrigerator,Remote Temperature Monitor for Hot Tub,Swimming Pool,-55 to 125 C,USB Connector (Matches with Ubibot WS1,WS1 Pro only)(3m)

POR SU ROBUSTEZ, en conjunto con el equipo UBUIBOT, HA SIDO DE GRAN UTILIDAD

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!

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.

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.

The cable thickness allows air leakage when used in a standard household freezer with mag gasket. A thinner ( or flatter ) cable would reduce the issue. Still experimenting to find a cure for the air leak.

No problems installing and using the sensor.

probe works as described and in my case, I can monitor room temperature as well as the pharmacy fridge. Works great.

Easy to setup and use and remarkable accurate as we have tested against other commercial devices.

Buen producto

The Ubibot unit is brilliant, sadly the USB connection to external probe isn't. 1st one broke not long after arriving, 2nd one already show signs of breaking. Disappointing as the rest is great

Can’t use this when you use mains power. Useless and expensive waste!
