What it is
The ShillehTek DS18B20 Waterproof Digital Temp Sensor Probe 1M for Arduino Pi is a sealed metal temperature probe that outputs stable digital readings over a 1‑Wire interface—ideal for Arduino and Raspberry Pi projects where analog noise is a problem. Its waterproof probe format suits aquariums, water tanks, outdoor experiments, fermentation, HVAC monitoring, and other wet/rough environments.
Pins
This DS18B20 temperature sensor probe uses a 1‑Wire connection and typically provides three leads for power, ground, and 1‑Wire data. Because wire colors and exact labeling can vary, refer to the listing photos and your project documentation for the correct lead identification before connecting.

Frequently Asked Questions
How do I wire a DS18B20 waterproof temperature sensor to an Arduino?
The DS18B20 probe uses a 1‑Wire connection and typically has power, ground, and a single data lead. Confirm the wire identification from the product photos, then connect the data lead to one Arduino digital pin and power/ground to the appropriate rails for your setup.
Can I connect multiple DS18B20 sensors to one Raspberry Pi GPIO pin?
Yes. A key benefit of the DS18B20 1‑Wire bus is that you can run multiple sensors on a single data pin and read each sensor separately in software.
Why choose a digital DS18B20 probe instead of an analog temperature sensor?
This probe outputs a digital temperature reading over 1‑Wire, which helps avoid analog noise and ADC variation. That makes it a solid choice for longer cable runs and electrically noisy projects.
Is this DS18B20 probe suitable for aquariums, fermentation, or outdoor use?
The sealed waterproof metal probe format is designed for wet or harsh environments, making it suitable for aquariums, water tanks, fermentation setups, HVAC monitoring, and outdoor experiments.
Where can I find the DS18B20 pinout or datasheet information?
Use the listing photos to confirm the lead identification for your probe, then consult DS18B20 datasheet resources and your Arduino/Raspberry Pi 1‑Wire library documentation for wiring and code examples.
