Multiple DS18B20

Other Hardware Sensors
1

Hi.

Does anyone know how to read multiple DS18B20 sensors. I can only seem to get one working. I am planning on adding a relay to this when I get the sensors working but at the moment I just want to get the two sensors displayed on an lcd. If anyone has done anything like this could you point me in the right direction as I'm new to this. I am using an arduino uno.

#include <DallasTemperature.h>
#include <OneWire.h>

OneWire oneWire(6); // pin D6
DallasTemperature sensors(&oneWire);
float temp1, temp2;

void setup() {
  Serial.begin(115200);
  Serial.println("DS18B20 thermometer");
  sensors.begin();
}

void loop() {
  sensors.requestTemperatures();
  temp1 = sensors.getTempCByIndex(0);
  temp2 = sensors.getTempCByIndex(1);
  
  Serial.print("Temp1 is ");
  Serial.print(temp1, 1); // one decimal place
//Serial.print(temp1, 4); // four decimal places
  Serial.println(" C");
  Serial.print("Temp2 is ");
  Serial.print(temp2, 1);
  Serial.println(" C\n");
}
