Product Overview

This is a pre-wired and waterproofed version of the DS18B20 digital temperature sensor. It is ideal for measuring temperatures in remote locations or wet environments. The sensor offers digital accuracy, eliminating signal degradation over long distances, and provides up to 12 bits of precision. It is compatible with 3.0-5.0V systems and can be connected to a single microcontroller pin, with multiple sensors addressable via their unique 64-bit IDs. A 4.7k ohm pullup resistor is included for setup.
