Wiring to a host controller

1.

🔽 Install Arduino IDE

Install the Arduino IDE

2.

📦 Install the library

Start the Arduino IDE, press the Sketch menu, and then Include Library > Manage Libraries. Search for DallasTemperature and install the library. There are also lots of other 1-Wire/DS18B20 libraries, any of them will work if you prefer.

3.

🔢 Code

Several example sketches can be found in File > Examples > Dallas Temperature in the Arduino IDE.

Be sure to change the code as needed for the specific wiring.

// Data wire is plugged into port 2 on the Arduino
#define ONE_WIRE_BUS 2

4.

➡️ Upload the code

Pick the board and port, then Upload the code.

5.

🔎 View the output

Open the Serial Monitor, measurements should be displayed in the monitor, with updates every second.

1-Wire/DS18B20 sensors are supported with native ESPHome components. You can read about usage on their website.
