The DS18B20 is a digital temperature sensor that it is cable of connecting multiple of sensors over the same bus. This sensor can be programmed using only few lines of code and it does not need calibration. It has 3 pins; GND for ground, DQ for data in/out, and VDD for power supply voltage. Its applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system.
