DS18B20 one-wire sensor

Hi all!

Has anyone used a CR1000 to log a set of DS18B20 one-wire temperature sensors? Any help would be appreciated.

Thanks,

You cannot physically connect them directly. You need to use a 1-Wire to RS232 adapter.

The adapter will have a manual that describes how RS232 commands correspond to 1-Wire commands. You also need to read the manual for the temperature sensor to see what commands you need to use and how the data is formatted. 

For an experienced programming, it would be two full days of work.
