Using a ds1820b isn't difficult - the onewire library will help you to do that. I have no idea what this means though:

only when the exothermic heat of a sensor changes

I think he means that the word for "temperature" he fed into Google Translate came out that way. XD

Once you spell the part number correctly, Google will take you to many worked examples showing how to read a temperature and print it to the serial port.
