Good sensor, careful with wiring
The sensor itself is accurate. Just make sure you have the pull-up resistor configured correctly on your data line.

Works but pin was bent
One of the header pins was slightly bent upon arrival. I straightened it out and it works fine now. Sensor readings are stable.
Q: Is this module waterproof?
A: The PCB module itself is not waterproof. The sensor probe version is, but this board is for general indoor use.
Q: Does it work with 3.3V logic?
A: Yes, it operates between 3.0V and 5.5V, so it is compatible with both 3.3V and 5V microcontrollers.
Q: What library do I need for Arduino?
A: You typically need the OneWire library and the DallasTemperature library.
Q: Can I connect multiple sensors to one GPIO pin?
A: Yes, the DS18B20 supports multiple devices on the same 1-Wire bus using unique addresses.
Q: What is the maximum cable length for the data line?
A: For reliable communication, keep wires under 50 meters. Longer distances may require additional shielding or resistors.
