Hello i have a probelm
I tryed to connect my ardoino uno with this temperatur sensor , but it did not work ,because for this divies there is no syntax that worked. I also tryed to use syntax from the same family for example the ds18B20 http://www.kriwanek.de/arduino/sensoren/165-temperatursensoren-dallas-ds18b20.html and ds18S20 http://www.pjrc.com/teensy/td_libs_OneWire.html. It is a divies ,witch use the OneWire Library and I also add this Libaray too. An other problems was that the datasheets i found were mixed with the newer divieces ds18b20 and ds18s20 https://cdn-reichelt.de/documents/datenblatt/A200/DS18S20%23MAX.pdf  http://www.produktinfo.conrad.com/datenblaetter/175000-199999/176168-da-01-en-TEMP_SENSOR_DS18S20_TO92_MAXIM_DALLAS_.pdf .I also tryed to use this syntax http://playground.arduino.cc/Learning/OneWire .I just want to connect the ds1820 with the arduino to collect tempertures.
Thank you for your responde

I guess the first thing you need to do is make certain that the sensor can use the same software as the DS18B20. It probably does, but this ensures you are talking the same language as everybody else.

Another approach is to try and use the sensor with no libraries - no one wire. This may sound dumb but, if you are only using one, it is valid, it works, and it might be your salvation.
