Waterproof DS18B20 Sensor Kit
A waterproof digital temperature sensor based on the popular DS18B20 chip. The stainless steel probe can be submerged in liquids or placed in harsh environments, making it ideal for monitoring aquariums, brewing, weather stations, and outdoor projects.
Uses the 1-Wire protocol, requiring only a single data pin to communicate with your microcontroller. Multiple sensors can share the same data line, each identified by a unique 64-bit address.
Key Features
- Waterproof Probe – Stainless steel housing for liquid and outdoor use
- 1-Wire Interface – Single data pin connection, supports multiple sensors on one bus
- High Accuracy – ±0.5°C from -10°C to +85°C
- Wide Range – Measures -55°C to +125°C (-67°F to +257°F)
- Configurable Resolution – 9 to 12-bit precision
- Unique ID – 64-bit address burned into each sensor
- Alarm Function – Built-in temperature-limit alarm system
Specifications
- Operating Voltage – 3.0–5.5V
- Probe Dimensions – 6mm diameter × 35mm long
- Cable Length – 90cm
- Cable Diameter – 4mm
- Query Time – Less than 750ms
Wiring
Wire colours may vary by batch:
- Type A: Red = VCC, Black = GND, Yellow = DATA
- Type B: Red = VCC, Yellow = GND, Green = DATA
Ideal For
- Aquarium and fish tank monitoring
- Home brewing temperature control
- Weather stations and outdoor sensors
- Raspberry Pi and Arduino projects
