Hi, > = > I managed to find the Dallas DS18S20 sensor (on the web, > it says DS1820, but I can't find that and somewhere I > read that DS1820 =3D DS18S20, is this right?) and also The DS18S20 is functionally equivalent to the DS1820 except for one point: = The = DS18S20 has a conversion time of max 750ms and the DS1820 has a maximum = conversion time of 500ms. If I remember correctly the DS18S20 is a newer de= sign = with improved performances and it is backward compatible with the DS1820 = (except for the conversion time). There is also a DS18B20 which is very similar but operates slightly differe= nt. = In this you can select the resolution for the temperature conversion to bet= ween = 9 and 12 bits (0.5 degrees to 0.0625 degrees). The higher the resulotion, t= he = longer the conversion time. = Regards / Ruben =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D Ruben J=F6nsson AB Liros Electronic Box 9124, 200 39 Malm=F6, Sweden TEL INT +46 40142078 FAX INT +46 40947388 ruben@pp.sbbs.se =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
