## Description

This waterproof DS18B20 digital temperature sensor delivers accurate readings over a simple 1-Wire interface, requiring just a single data pin on your microcontroller. The sealed probe and silicone lead wire make it ideal for measuring temperatures in wet environments, outdoors, or at a distance from your controller. Each sensor has a unique 64-bit serial code, allowing multiple DS18B20 sensors to share the same 1-Wire bus. This makes it straightforward to build distributed temperature monitoring systems using a single GPIO pin on an Arduino or Raspberry Pi. Key Features Waterproof Probe – Sealed stainless steel housing for wet and outdoor environments 1-Wire Interface – Only one data pin required; multiple sensors can share the same bus Configurable Resolution – 9 to 12-bit selectable precision Wide Temperature Range – Measures from −55°C to +125°C (operating accuracy ±0.5°C from −10°C to +85°C) Digital Output – No signal degradation over long cable runs Unique 64-Bit ID – Each sensor individually addressable for multi-sensor setups Silicone Lead Wire – Heat-resistant cabling rated to 125°C Wide Supply Voltage – 3V to 5.5V operation Wiring Red – VCC (3–5.5V) Black – GND Blue – DATA (1-Wire) Ideal For Aquarium, pool, and water temperature monitoring Weather stations and outdoor environmental sensing HVAC and building climate control systems Homebrew and fermentation temperature tracking Arduino and Raspberry Pi projects Package Contents 1× Waterproof SMD DS18B20 Digital Temperature Sensor Resources DS18B20 Datasheet (PDF) OneWire Library for Arduino
