Hi @TE-KarlKomierowski
Thank you very much for your reply.
I would like to share the sketch. I downloaded the library from Arduino Manage libraries.
This is my sketch,
#include <OneWire.h>
//int DS18S20_Pin;
int DS18S20_Pin = attachInterrupt (digitalPinToInterrupt (05), connect, RISING); //DS18S20 Signal pin on
//x = digitalPinToInterrupt (D07);
//attachInterrupt (x, ISR, mode);
//int DS18S20_Pin = PIN_D07;
//DS18S20_Pin.attach(PIN_D07);
//Temperature chip i/o
OneWire ds(digitalPinToInterrupt (05), connect, RISING); // on digital pin 2
void setup(void) {
Serial.begin(9600);
}
void loop(void) {
float temperature = getTemp();
Serial.println(temperature);
delay(1000); //just here to slow down the output so it is easier to read
}
float getTemp(){
//returns the temperature from one DS18S20 in DEG Celsius
byte data[12];
byte addr[8];
if ( !ds.search(addr)) {
//no more sensors on chain, reset search
ds.reset_search();
return -1000;
}
if ( OneWire::crc8( addr, 7) != addr[7]) {
Serial.println("CRC is not valid!");
return -1000;
}
if ( addr[0] != 0x10 && addr[0] != 0x28) {
Serial.print("Device is not recognized");
return -1000;
}
ds.reset();
ds.select(addr);
ds.write(0x44,1); // start conversion, with parasite power on at the end
byte present = ds.reset();
ds.select(addr);
ds.write(0xBE); // Read Scratchpad
for (int i = 0; i < 9; i++) { // we need 9 bytes
data[i] = ds.read();
}
ds.reset_search();
byte MSB = data[1];
byte LSB = data[0];
float tempRead = ((MSB << 8) | LSB); //using two's compliment
float TemperatureSum = tempRead / 16;
return TemperatureSum;
}
This is simple sketch given by DFRobot temperature sensor.

I appreciate your kind support.
Thank you!
