DS18B20 Digital Temperature Sensor DIP – 1-Wire, ±0.5°C

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.
