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.

Like a new bed.
Color: White, Size: Queen
Surprising how small the box it was delivered in. As the packaging is removed, the topper grows to full size. Easy to install. Very comfortable to sleep in. Getting into and out of a bed that is four inches taller takes some getting used to.
