Waterproof SMD DS18B20 Digital Temperature Sensor
This waterproof DS18B20 digital temperature sensor delivers accurate readings over a simple 1-Wire interface, requiring just a single data pin on your microcontroller. The sealed probe and silicone lead wire make it ideal for measuring temperatures in wet environments, outdoors, or at a distance from your controller.
Each sensor has a unique 64-bit serial code, allowing multiple DS18B20 sensors to share the same 1-Wire bus. This makes it straightforward to build distributed temperature monitoring systems using a single GPIO pin on an Arduino or Raspberry Pi.
Key Features
- Waterproof Probe – Sealed stainless steel housing for wet and outdoor environments
- 1-Wire Interface – Only one data pin required; multiple sensors can share the same bus
- Configurable Resolution – 9 to 12-bit selectable precision
- Wide Temperature Range – Measures from −55°C to +125°C (operating accuracy ±0.5°C from −10°C to +85°C)
- Digital Output – No signal degradation over long cable runs
- Unique 64-Bit ID – Each sensor individually addressable for multi-sensor setups
- Silicone Lead Wire – Heat-resistant cabling rated to 125°C
- Wide Supply Voltage – 3V to 5.5V operation
Wiring
- Red – VCC (3–5.5V)
- Black – GND
- Blue – DATA (1-Wire)
Ideal For
- Aquarium, pool, and water temperature monitoring
- Weather stations and outdoor environmental sensing
- HVAC and building climate control systems
- Homebrew and fermentation temperature tracking
- Arduino and Raspberry Pi projects
