The 1-Wire bus protocol, which is utilized by the DS18B20, only needs one control signal for communication. To avoid the bus port being in a 3-state or high-impedance condition, the control signal line needs a wake-up pull-up resistor (the DQ signal line is on the DS18B20). The microcontroller (master device) in this bus system recognizes the bus's devices by their 64-bit serial numbers. A bus may potentially support a limitless number of devices because each one has a distinct serial number.
The DS18B20 uses the 1-Wire bus protocol, which requires only one control signal for communication. The control signal line needs a wake-up pull-up resistor to prevent the port connected to the bus from being in a 3-state or high-impedance state (the DQ signal line is on the DS18B20). In this bus system, the microcontroller (master device) identifies the devices on the bus through each device's 64-bit serial number. Because each device has a unique serial number, the number of devices connected to a bus can theoretically be unlimited.
