Perfect for Arduino Projects
These sensors work flawlessly with my Arduino setup. The 1-wire protocol makes wiring very simple, and the temperature readings are consistent and accurate.

Good value for bulk purchase
Bought a pack for a home automation project. Most of them worked perfectly out of the box. One had a slightly loose pin, but overall great value for the price.

Reliable for soil monitoring
I waterproofed these myself and buried them in my garden beds. They have been running for three months without any drift in data. Highly recommended.

Easy to code for
As a beginner, I found plenty of libraries available for this chip. It responded immediately to my test sketches. Great learning component.

Solid performance
We used these in our robotics competition bot. They handled the voltage fluctuations well and provided fast enough updates for our needs.
Q: Can I connect multiple sensors to a single GPIO pin?
A: Absolutely. The DS18B20 supports multi-drop capability, allowing you to connect many sensors to one data line, each identified by a unique serial number.
Q: What is the maximum cable length for reliable operation?
A: While it depends on cable quality and environment, standard practice suggests keeping cables under 50 meters for optimal signal integrity without additional buffering.
Q: How do I identify individual sensors if I daisy-chain them?
A: Each chip comes factory-programmed with a unique 64-bit ROM code. You can use a search command in your code to list and address each sensor individually.
Q: Is this compatible with 3.3V logic systems like Raspberry Pi?
A: Yes, the DS18B20 operates between 3.0V and 5.5V, making it directly compatible with 3.3V systems such as the Raspberry Pi.
Q: Does this sensor require an external pull-up resistor?
A: Yes, for reliable communication on the 1-Wire bus, a 4.7kΩ pull-up resistor between the data line and VCC is strongly recommended.
