DS18B20 Temperature Sensor

The DS18B20 Temperature Sensor is a highly accurate, digital thermometer sensor widely used for measuring temperatures in a variety of applications. It communicates via a 1-Wire bus, requiring only one data line (and ground) for communication with microcontrollers such as Arduino, Raspberry Pi, ESP32, and others. The sensor can measure temperatures from -55°C to +125°C with an accuracy of ±0.5°C over a wide range. Its unique 64-bit serial code allows multiple sensors to be connected on the same bus, enabling efficient temperature monitoring in complex systems. The DS18B20 is waterproof (in certain models), durable, and ideal for environmental monitoring, home automation, industrial control, and weather stations.
