DS18B20 Digital Temperature Sensor The DS18B20 is a high-precision digital thermometer providing 9 to 12-bit Celsius temperature measurements. It communicates over a 1-Wire bus, requiring only one data line (and ground) for communication with your microcontroller. Each sensor has a unique 64-bit serial code, allowing multiple DS18B20s to function on the same bus—perfect for multi-point environmental monitoring.
