Temperature sensors DS1820

[PortlandJohn]

Can someone tell me what the difference is between DS1820, DS18B20 and a DS18S20. I can get the DS18B20 to work fine but the same program does not work with a DS18S20.

Cheers all

Why not try the manufacturers website?

Hi, John

Just found that :

<< Specification Differences: The primary specification difference between the two parts is the temperature conversion time: DS1820 = 500ms (max) and DS18S20 = 750ms (max). >>

hope it helps.
