Replaces / Cross-Reference Part Numbers
- Direct replacement for any application using a DS18B20 sensor IC in a waterproof probe configuration.
Compatibility & Fitment
- Compatible with microcontrollers and single-board computers supporting the 1-Wire interface, including Arduino, Raspberry Pi, ESP8266, and ESP32.
- Designed for measuring temperature in liquids, soil, and other wet or humid environments.
- The 6mm probe diameter fits standard thermowells and mounting hardware.
When to Replace
- Sensor fails to appear on the 1-Wire bus.
- Temperature readings are erratic, consistently incorrect, or do not update.
- Visible physical damage to the cable, heat-shrink seal, or stainless steel probe.
Installation Tips
- A 4.7kΩ pull-up resistor is required between the Data and VCC lines for stable communication.
- Connect wires to the corresponding VCC, GND, and data pins on your controller.
- Ensure the 1-Wire interface is enabled in your device's software configuration (e.g., raspi-config for Raspberry Pi).
- Multiple sensors can be connected to the same data pin due to their unique addresses.
