Great for learning about digital sensors. Documentation online is plentiful.

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.
