#19037 - RE: Circuit for multiple DS1820
Hi Luccus,

there is no special circuit diagram needed. Simple connect all sensors in parallel and use a common pull up resistor (e.g. 2.2kOhms)

A software example can be found at:

Also its possible to use only 2 wire with parasite power. Then only a P-channel FET (e.g. BS250) was needed to switch on power during temperature conversion.
