Exactly what I needed
Using this to monitor soil temperature indirectly. It's been running outdoors in a sealed enclosure for two weeks without issues. Very satisfied with the build quality.

Good value, fast shipping
The sensor is accurate enough for my home automation greenhouse project. I deducted one star because the included cable is a bit short, but otherwise, it's a great product.

Perfect for Arduino projects
This module works flawlessly with my Arduino Uno. The wiring is straightforward, and the library support is excellent. Readings are stable and match my reference thermometer.

Easy for beginners
As someone new to electronics, I found this very easy to set up. The pinout is clearly labeled on the board, and there are plenty of tutorials online for the DS18B20.

Solid performance
Response time is quick and the 1-wire protocol saves GPIO pins on my ESP32. Just remember to enable the internal pull-up resistor in your code if you don't use an external one.

Reliable industrial grade feel
I've used these in several prototype builds. They handle voltage fluctuations well and the waterproof probe option pairs nicely with this breakout board. Highly recommended.
Q: Does this module come with a waterproof probe?
A: No, this listing is for the bare DS18B20 breakout board only. The waterproof steel probe version is sold separately.
Q: What library do you recommend for Raspberry Pi?
A: For Raspberry Pi, we recommend using the W1 Thermodriver built into the Linux kernel or the Adafruit CircuitPython DS18x20 library for Python scripts.
Q: Is the 3-pin cable included in the box?
A: Yes, the package includes one 3-pin PH2.0 jumper cable to help you get started immediately.
Q: Can I connect multiple sensors to a single data pin?
A: Yes, the DS18B20 supports multi-drop capability. You can connect multiple modules to the same data line, provided each has a unique serial ID and you use an appropriate pull-up resistor.
Q: What is the maximum cable length for reliable readings?
A: While the 1-Wire protocol can theoretically support long distances, for reliable high-speed readings without signal degradation, we recommend keeping the cable under 10 meters or using a shielded cable with a strong pull-up resistor.
