12/17/2023 0 Comments One wire arduino libraryWe also have to add a 4.7 kΩ pull-up resistor between the Data pin and 5 V, which will keep the idle state for the 1-Wire bus high.ĭallasTemperature library install for DS18B20 Sensor Now we need to connect the Data pin (DQ) to any of the digital pins of the Arduino, here I used digital pin D2. We have to start the connection by connecting the GND pin of the sensor to the ground pin of the Arduino and the Vcc pin of the sensor to the 5 V output of the Arduino. How to Connect DS18B20 Temperature Sensor with Arduino (Circuit Wiring)Ĭonnecting a DS18B20 temperature Sensor to the Arduino is very easy, as we only need to connect 3 pins.
