DS18B20 Waterproof Digital Temperature Probe: Precision Meets Durability

Elevate your project with the DS18B20 Waterproof Digital Temperature Probe sensor, a robust solution tailored for demanding environments. Whether you’re monitoring systems far away or amidst wet conditions, this pre-wired sensor combines convenience with performance. Its waterproof design ensures reliability up to 125°C, with a PVC-jacketed cable recommended for temperatures below 100°C. Digital accuracy means signal integrity is maintained across distances without degradation.

Key Features

• Enhanced Durability: With a stainless steel tube and waterproof design, measure confidently in various conditions.
• High Precision: Offers ±0.5°C accuracy across a broad temperature range (-55 to 125°C) and up to 12 bits of precision.
• Digital Communication: Utilizes the Dallas 1-Wire protocol for seamless microcontroller integration, supporting both 3.0V and 5.0V systems.
• Unique Identification: Each sensor is equipped with a unique 64-bit ID, allowing multiple sensors to operate on a single digital pin.
• Ready to Use: Comes with a 4.7k resistor for the required DATA to VCC line pull-up, facilitating immediate setup.

Cable and Sensor Details

• Cable Length: 2m with cable and Sensor with a 4mm diameter for flexible installation.
• Sensor Housing: Durable stainless steel tube (6mm diameter by 50mm long).
• Connection Simplicity: Color-coded wires ensure straightforward connections, compatible with both three and four-wire setups.

Technical Specifications

• Temperature Range: -55 to 125°C, with selectable resolution from 9 to 12 bits.
• Interface: 1-Wire protocol, ensuring a minimal digital footprint.
• Accuracy: ±0.5°C from -10°C to +85°C, featuring a temperature-limit alarm for critical monitoring.
• Query Time: Rapid response with a query time of less than 750ms.

Application Notes

Ideal for a wide range of applications but not suited for salt water or corrosive environments. While the 1-Wire protocol offers rich features, it requires specific libraries for operation. We recommend starting with the Dallas Temperature Control Arduino library alongside the OneWire Library for an efficient kick-off to your project.

Dive into precise, durable temperature monitoring with the waterproof DS18B20 sensor, and unlock new possibilities in environmental sensing. Perfect for hobbyists and professionals alike, this sensor blends precision, durability, and ease of use into a compact, reliable package.

Suitable for outdoor use

The DS18B20 Waterproof Digital Temperature Probe temperature sensor is equipped with a 1-wire interface. As a result, the sensor only needs one port pin to communicate with a microcontroller. Since the sensor has its own unique 64-bit address, it can work with one or two other sensors on the same single-wire bus. Thanks to the cable length of 1 meter, you have sufficient leeway when installing the temperature sensor. Thanks to the stainless steel housing and waterproof cable , the sensor is also very suitable for outdoor use. It does not require external power The DS18B20 temperature sensor can derive its operating current directly from the data line. Experts call this “Parasitic Power”. This makes an external power supply superfluous. Quick connection and installation in THE SMART HOME is possible with the quick start guide.
