1/5PCS DS18B20 Waterproof Thread Temperature Probe – Stainless Steel, 1/2/3/5 m Cable Length – Ideal for Arduino Projects
Product Overview
Designed for precision temperature monitoring in harsh environments, the DS18B20 waterproof thread temperature probe combines a rugged stainless‑steel sheath with a fully sealed waterproof design. Whether you’re building a weather station, a smart home thermostat, or an industrial temperature logger, this sensor delivers reliable, accurate readings from -55 °C to +125 °C (‑67 °F to 257 °F) over distances up to 5 meters.
Key Highlights
- ✅ Waterproof (IP68) construction – perfect for outdoor, liquid, or humid applications.
- ✅ Stainless‑steel thread – corrosion‑resistant and durable for long‑term use.
- ✅ Multiple cable lengths – choose 1 m, 2 m, 3 m, or 5 m to suit your project layout.
- ✅ One‑wire digital interface – simple wiring, supports up to 8 sensors on a single Arduino pin.
- ✅ High accuracy – ±0.5 °C from –10 °C to +85 °C, with 12‑bit resolution for fine detail.
- ✅ Plug‑and‑play with Arduino – compatible with the
OneWireandDallasTemperaturelibraries.

Why Choose This DS18B20 Probe?
When accuracy, durability, and ease of use matter, our waterproof DS18B20 sensor stands out. The stainless‑steel thread protects against corrosion, while the IP68 sealing ensures reliable performance in rain, pools, or industrial fluids. Its flexible cable lengths let you place the sensor exactly where you need it—no extra extension cables required.
Installation Tips
- Connect the red wire to 5 V, black to GND, and yellow (or white) to a digital I/O pin on your Arduino.
- Install the
OneWireandDallasTemperaturelibraries via the Arduino Library Manager. - Use a 4.7 kΩ pull‑up resistor between the data line and 5 V for stable communication.
- Secure the sensor in place with a zip‑tie or silicone sealant for extra protection.
