Description

This sensor is a waterproof version of the popular DS18B20 digital temperature sensor, perfect for measuring temperatures in remote or wet environments. The sensor accurately measures up to 125°C, but due to its PVC-jacketed cable, we recommend operating it below 100°C for longevity.

Thanks to its digital 1-Wire interface, you’ll experience no signal degradation even over long cable runs. The DS18B20 delivers configurable 9 to 12-bit temperature readings and works seamlessly with 3.0–5.5V systems. Only one data wire plus ground is required for connection to your microcontroller.

Each sensor has a unique silicon serial number, allowing you to connect multiple DS18B20 sensors on the same 1-Wire bus—ideal for applications like HVAC systems, indoor climate monitoring, equipment temperature sensing, and industrial process control.
