Solid performance
Using this in a smart home project to monitor the basement. It handles the humidity well and the digital signal prevents noise interference over the cable.

Perfect for Arduino Projects
This DS18B20 module worked flawlessly with my Arduino Uno. The wiring was simple, and the library support is excellent. Readings are consistent and match my calibrated thermometer.

Easy to use for beginners
As someone new to electronics, I was worried about the setup. However, there are plenty of tutorials online, and this module made it very easy to get started with temperature sensing.

Reliable and Accurate
I bought five of these for a multi-point temperature logging system. All sensors returned identical readings in the same environment, which shows great consistency.

Good value, fast shipping
The sensor works well for monitoring room temperature. The only reason for 4 stars is that the wires are a bit short for my specific enclosure, but I can extend them easily.
Q: Does this module require an external pull-up resistor?
A: Most versions of this module include an onboard 4.7kΩ pull-up resistor, so you generally do not need to add one externally. Please check the specific PCB layout upon arrival to confirm.
Q: What libraries are compatible with this sensor?
A: For Arduino, the 'DallasTemperature' library combined with 'OneWire' is the most popular and reliable choice. For Raspberry Pi, it can be enabled via the w1-gpio kernel module.
Q: Can I connect multiple sensors to a single data pin?
A: Yes, the DS18B20 supports multi-drop capability. You can connect multiple sensors to the same data line, provided each has a unique serial ID, which they do from the factory.
Q: What is the maximum cable length recommended?
A: While the 1-Wire protocol can theoretically support longer distances, we recommend keeping cables under 50 meters for stable communication without signal degradation. Shorter is always better for reliability.
Q: Is this waterproof for outdoor use?
A: The standard module shown is not waterproof. For outdoor or wet environments, we recommend purchasing the stainless steel probe version of the DS18B20 which is sealed.
