1-Wire Bus Protocol Temperature Sensor For Robot Industrial

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.
