The DS18B20 Waterproof Temperature Probe is a durable and reliable sensor designed to measure temperatures in challenging environments, particularly in wet or distant locations. With its stainless steel encapsulation, the probe is highly resistant to moisture, corrosion, and physical damage, making it perfect for applications that require long-term durability and accuracy.
- Waterproof and Durable Design: Encapsulated in a 6mm diameter, 30mm long stainless steel tube, the probe offers excellent protection against water and rust, ensuring reliable performance in wet conditions.
- High Accuracy and Precision: The DS18B20 sensor provides precise temperature measurements with an accuracy of ±0.5°C across most of its range. It offers up to 12-bit resolution for fine temperature readings.
- Digital Output with No Signal Degradation: The digital nature of the sensor ensures that there is no signal degradation even over long distances, making it ideal for remote temperature sensing.
- 1-Wire Communication: This sensor uses a 1-wire communication protocol, which means that multiple sensors can be connected to a single digital pin on a microcontroller. Each sensor has a unique 64-bit ID for easy identification.
- Wide Voltage Compatibility: Compatible with both 3.0V and 5.0V systems, making it versatile for use with a wide range of microcontrollers and development platforms.
- Temperature Alarm System: The sensor includes a programmable temperature-limit alarm system, allowing users to set specific thresholds for triggering actions when temperature limits are exceeded.
- Probe Length: 1 meter (±3% tolerance)
- Probe Diameter: 6mm
- Probe Length: 30mm (stainless steel casing)
- Accuracy: ±0.5°C across -10°C to +85°C range
- Resolution: Selectable between 9 to 12 bits
- Communication Protocol: 1-Wire interface
- Operating Voltage: 3.0V to 5.0V
- Unique ID: 64-bit factory-burned ID
- Waterproof Rating: Yes
- Operating Range: -55°C to +125°C
- Red: VCC/VDD
- Yellow/White: DATA (Requires a 4.7k pull-up resistor between DATA and VCC)
- Black: GND
- Industrial and Commercial Temperature Monitoring: Suitable for monitoring temperature in industrial processes, storage rooms, or refrigerators.
- Environmental Monitoring: Used for measuring soil or water temperature in agricultural or environmental systems.
- Home Automation: Ideal for use in HVAC systems or smart home temperature monitoring.
- Medical and Laboratory Applications: Accurate temperature sensing for research and healthcare equipment.
- Aquariums and Outdoor Installations: Reliable performance in wet and submerged environments, perfect for use in aquariums, ponds, and outdoor installations.
- No Signal Degradation: Since the sensor provides digital readings, there is no loss of accuracy even when used with long cable runs.
- Multi-Sensor Capability: Multiple DS18B20 sensors can be connected to the same microcontroller pin, thanks to the 1-wire protocol and unique ID for each sensor.
- Resistant to Harsh Environments: The stainless steel housing and waterproof design make it highly resistant to corrosion, moisture, and rough conditions.
