Okay for the price
Does the job. Cable could be longer for my specific application but otherwise functional.

Good but needs resistor
Works well but beginners might struggle without knowing about the pull-up resistor requirement.
Q: Is the entire cable waterproof?
A: Only the stainless steel probe tip is waterproof. Do not submerge the cable or board.
Q: Does this work with 3.3V logic?
A: Yes, the sensor operates comfortably within 3.0V to 5.5V range.
Q: Is there a library for ESP32?
A: Yes, the standard DallasTemperature library works perfectly with ESP32 boards.
Q: What resistor value is needed?
A: A 4.7k ohm pull-up resistor between VCC and Data line is recommended.
Q: Can I daisy chain multiple probes?
A: Yes, you can connect multiple DS18B20 sensors on the same data line.
