You can use the preceding links or go directly to MakerAdvisor. Schematic The sensor can operate in two modes: Normal mode: 3-wire connection is needed. You provide power to the VDD pin. The sensor derives its power from the data line. Follow the next steps to install those libraries. Installing Libraries 1. The Library Manager should open. After installing the needed libraries, upload the following code to your Arduino board.
This sketch is based on an example from the Dallas Temperature library. You can have more than one IC on the same bus. You need to call the requestTemperatures method before getting the actual temperature value.
If you have more than one sensor, you use index 0 for the first sensor, index 1 for the second sensor, and so on. New temperature readings are requested every second. You should get the temperature displayed in both Celsius and Fahrenheit: Getting Temperature from Multiple DS18B20 Sensors The DS18B20 temperature sensor communicates using one-wire protocol and each sensor has a unique bit serial code, so you can read the temperature from multiple sensors using just one single Arduino digital Pin.
Schematic To read the temperature from multiple sensors, you just need to wire all data lines together as shown in the following schematic diagram: Upload Code — Multiple DS18B20 Then, upload the following code. It scans for all devices on Pin 4 and prints the temperature for each one. This sketch is based on the example provided by the DallasTemperature library.
So each sensor can be identified by its address. Then, you use the getTempC method that accepts as argument the device address. You can use one sensor or multiple sensors on the same data line because you can identify each sensor by its unique address.
Now, you can take this project further and display your sensor readings in an OLED display , for example. We have more tutorials for other Arduino compatible sensors that you may find useful:.

Gutaxe This makes it great for use as an external sensor. However, the DS18B20 can also extract its power from the data line which means we only effectively need two wires to connect it up.
