Setup a oneWire instance to communicate with any OneWire devices ![]() #include // Data wire is plugged into port 2 on the Arduino It is recommended that you connect only one sensor at a time so that you can find each sensor’s address and assign it a name. The sketch below detects all DS18B20s on the bus and prints their one-wire addresses on the serial monitor. Because each DS18B20 is pre-programmed with a unique 64-bit serial code, they can be distinguished from one another. Finding the Addresses of DS18B20s on a Bus Arduino Interfacing Multiple DS18B20 Digital Temperature Sensors with Arduino One of the DS18B20’s features is that multiple DS18B20s can coexist on the same 1-Wire bus. So we’ll use one sketch to find and record the address of each sensor, and then another sketch to read each sensor individually. print(DallasTemperature:: toFahrenheit(tempC)) Įach DS18B20 is programmed with a unique 64-bit address at the time of manufacture, allowing them to be distinguished from one another. print(( char) 176) //shows degrees character Display temperature from each sensor for ( int i = 0 i < deviceCount i++) Send command to all the sensors for temperature conversion Pass oneWire reference to DallasTemperature library Setup a oneWire instance to communicate with any OneWire device #include // Data wire is plugged into digital pin 2 on the Arduino ![]()
