![]() ![]() The DS18B20 temperature sensor is also available in waterproof version. ![]() So, you can get temperature from multiple sensors using just one Arduino digital pin. This allows you to wire multiple sensors to the same data wire. The following table shows how you should wire the DS18B20 sensor to your Arduino board: DS18B20Īny digital pin (with 4.7k Ohm pull-up resistor)Įach DS18B20 temperature sensor has a unique 64-bit serial code. It can be powered by an external power supply or it can derive power from the data line (called “parasite mode”), which eliminates the need for an external power supply. This means that it just requires one data line (and GND) to communicate with the Arduino. The DS18B20 temperature sensor is a one-wire digital temperature sensor.
