How It Works
The DS18B20 measures temperature through its stainless steel probe and sends digital temperature data through the 1-Wire DATA line. The sensor connects to a microcontroller using VCC, GND, and DATA wires. A 4.7kΩ pull-up resistor is required between DATA and VCC for stable communication.
Multiple DS18B20 sensors can be connected to the same data pin because each sensor has a unique address.
