Description
The DS18B20 is a digital temperature sensor in a TO-92 (DIP) package designed for precise temperature measurement in embedded systems. It communicates using a 1-Wire interface, requiring only a single data line for operation. Each sensor features a unique 64-bit serial code, allowing multiple sensors to operate on the same bus. This is the standard non-waterproof version, intended for PCB mounting or enclosed environments, and is suitable for data logging, thermostatic control, and industrial monitoring applications. Features • Digital temperature sensor in TO-92 DIP package • 1-Wire interface using single data line • Unique 64-bit serial number per device • Supports multiple sensors on one bus • User-selectable 9 to 12-bit resolution • ±0.5°C accuracy from –10°C to +85°C • Wide temperature range –55°C to +125°C • Parasite power support via data line • Nonvolatile high and low alarm registers • No external components required • Designed for PCB mounting applications Case for ds18b20 temperature sensor module Tutorials • How To Use DS18B20 Temperature Sensor • Raspberry Pi DS18B20 Temperature Sensor Tutorial
