## Description

A waterproof DS18B20 digital temperature sensor kit with everything you need to connect to an Arduino. The stainless steel probe measures temperatures from -55°C to +125°C over a 1-Wire interface, requiring just one digital pin for communication. Multiple sensors can share the same data pin thanks to unique 64-bit IDs. The kit includes a terminal sensor adapter for easy plug-and-play connection to Arduino — no breadboard wiring required. Key Features Waterproof Probe – Stainless steel housing for immersion in liquids 1-Wire Interface – Only one digital pin needed for data Multi-Sensor Support – Multiple probes can share a single data pin Wide Temperature Range – -55°C to +125°C (-67°F to +257°F) Configurable Resolution – 9 to 12-bit temperature readings Terminal Adapter Included – Easy connection to Arduino without soldering Specifications Sensor – DS18B20 Operating Voltage – 3.0–5.5V Accuracy – ±0.5°C (-10°C to +85°C) Temperature Range – -55°C to +125°C Resolution – 9 to 12-bit (configurable) Query Time – <750 ms Probe Dimensions – 6 mm diameter × 35 mm long (stainless steel) Cable Length – 90 cm Cable Diameter – 4 mm Wiring Type A: Red = VCC, Black = GND, Yellow = DATA Type B: Red = VCC, Yellow = GND, Green = DATA Package Contents 1× Waterproof DS18B20 temperature probe 1× Terminal sensor adapter (DFR0055) 1× Digital sensor cable Ideal For Water temperature monitoring (aquariums, pools, brewing) Environmental and weather station projects Arduino and Raspberry Pi temperature logging Industrial and outdoor temperature sensing Resources DFRobot Wiki
