DS18S20 instead of DS18B20 gives the wrong value. How I can manage It?

Hi,
I know that is because the B20 differs from S20, but could u recomend, how I can get correct temp? Now I have 3,25 °C when real temp is ~25. Will It be correct to just multiple to some koef. and\or shift the value?
Sorry for possible offtop.
Thanks.

Hi, I think there is a thread on this here: http://forum.espruino.com/conversations/317/#comment3172

Please let me know how you get on - it'd be nice to improve the DS18B20 library so it works with both

Hello Andrey,
for me it works this way. Type of sensor can be recognized in device info of sensor

function OneWireTemp(pin){
  var me = this;
  me.ow = new OneWire(pin);
  me.device = me.ow.search()[0];
  me.deviceType = me.device - ((me.device >> 8) << 8);
  me.readRegister = function(callback,n){
    if(!n)n = 8;
    var reg = [];
    me.ow.reset();me.ow.select(me.device);me.ow.write(0x44,true);
    me.ow.reset();me.ow.select(me.device);me.ow.write(0xBE);
    for(var i = 0; i < n; i++){reg.push(me.ow.read());}
    return reg;
  };
  me.getTemp = function(callback){
    var t,reg = me.readRegister(2);
    t = reg[0] + (reg[1] << 8); if(t > 32767) t -= 65536;
    switch(me.deviceType){
      case 40: t = t / 16; break;//ds18B20
      case 16: t = t / 2; break;//ds18S20
    }
    return t;
  };
}

Hi JumJum,

Thanks! By the way, when you post code in the forum please could you surround it with 3 backticks? See https://help.github.com/articles/github-flavored-markdown#fenced-code-blocks

I've just updated your post above, and it makes it syntax highlight correctly :)
