Connect the digital temperature sensor DALLAS DS18B20 to arduino resistor on 220 Оm
#include
// DS18B20 pin 2.
OneWire ds(2);
void setup() {
// Start reading port.
Serial.begin(9600);
}
void loop() {
byte data[2];
ds.reset();
ds.write(0xCC);
ds.write(0x44);
delay(750);
ds.reset();
ds.write(0xCC);
ds.write(0xBE);
data[0] = ds.read();
data[1] = ds.read();
int Temp = (data[1]<<8)+data[0];
Temp = Temp>>4;
// Output temperature values to the console.
Serial.print(" T = ");
Serial.print(Temp);
Serial.println("'C");
