Ubibot DS18B20 Waterproof Temperature Probe – For Refrigerator, Hot Tub, Pool Monitoring

Need to keep an eye on temperatures in tricky spots? This Ubibot DS18B20 probe is your answer. It's a waterproof sensor made from stainless steel, so it won't rust even in wet places like swimming pools, hot tubs, refrigerators, or greenhouses. It measures temps from -55°C to +125°C (that's -67°F to 257°F!) with an accuracy of ±0.5°C between -10°C and 85°C. The cable comes in 3m or 5m lengths (you pick), and it has a handy Micro USB connector that plugs right into Ubibot WS1 or WS1 Pro monitors. Once connected, you can see the temperature readings remotely via the app or web console and even set up custom alerts if things get too hot or cold. Setup takes seconds—just plug and go. Perfect for checking your fridge's temp, making sure your pool isn't freezing, or monitoring a grow tent. Reliable, easy to use, and built for tough conditions.
