A pre-wired DS18B20 digital temperature sensor on a breakout module with three labelled pins for easy connection. The DS18B20 uses the 1-Wire protocol, requiring only a single data line to communicate temperature readings to a microcontroller such as a Raspberry Pi, Arduino, or micro:bit.

Key Features

• Temperature Range – -55°C to +125°C
• Accuracy – ±0.5°C from -10°C to +85°C
• Resolution – Configurable from 9 to 12 bits
• 1-Wire Protocol – Single data pin; each sensor has a unique 64-bit address for multi-sensor buses
• Operating Voltage – 3.0 V to 5.5 V
• Three-Pin Module – GND (−), Data (Out), and VCC (+)

Ideal For

• Weather stations and environmental monitoring
• Aquarium and greenhouse temperature logging
• Multi-sensor temperature networks (daisy-chain multiple sensors on one data line)
