Good accuracy
Using it for my greenhouse. Needs a pull-up resistor sometimes depending on wiring.

5 FAQ
Q: Can I connect multiple sensors to one pin?
A: Yes, the 1-Wire protocol allows multiple devices on the same data line.
Q: What is the conversion time?
A: Typically 750ms for a full 12-bit conversion.
Q: Does it work with 3.3V logic?
A: Yes, it operates between 3.0V and 5.5V, so it is compatible with 3.3V systems.
Q: Is this waterproof?
A: The chip itself is not waterproof. You need a stainless steel probe version for water immersion.
Q: What resistor value is needed?
A: Typically a 4.7kΩ pull-up resistor between VCC and Data line is recommended.
