How It Works
The DS18B20 communicates with the microcontroller using the 1-Wire digital communication protocol. Unlike analog temperature sensors, the temperature conversion is performed internally, and the resulting digital value is transmitted directly to the microcontroller.
Multiple DS18B20 sensors can be connected to the same data line, with each sensor identified by its unique 64-bit address. This makes the sensor particularly useful for applications requiring temperature measurements at multiple locations.
