## Description

A waterproof DS18B20 digital temperature probe with a 0.5m cable and XH2.54mm connector. Ideal for monitoring temperatures in wet or harsh environments including aquariums, hydroponics, brewing, and outdoor weather stations. The DS18B20 is a popular one-wire digital temperature sensor that communicates over a single data line, making it easy to use with Arduino, Raspberry Pi, and ESP32 microcontrollers. Multiple sensors can share the same data bus for multi-point temperature monitoring. Key Features Waterproof Stainless Steel Probe – Sealed housing for use in liquids and outdoor environments Wide Temperature Range – Measures from −55°C to +125°C ±0.5°C Accuracy – High accuracy in the −10°C to +85°C range One-Wire Digital Interface – Single data line with unique 64-bit serial code per sensor XH2.54mm Connector – Plug-in connection for easy integration 0.5m Cable Length – Flexible lead for convenient sensor placement Specifications Sensor – DS18B20 Temperature Range – −55°C to +125°C Accuracy – ±0.5°C (−10°C to +85°C) Resolution – 9 to 12-bit configurable Interface – One-Wire (Dallas/Maxim) Cable Length – 0.5m Connector – XH2.54mm Ideal For Aquarium and hydroponic temperature monitoring Home brewing and fermentation control Outdoor weather stations Arduino and Raspberry Pi sensor projects Package Contents 1× Waterproof DS18B20 Temperature Probe (0.5m cable with XH2.54mm connector) Note: A 4.7kΩ pull-up resistor on the data line is typically required for reliable one-wire communication.
