Hello
Sorry for my English.
I have un Sistem for the control of temperatures of the schoolroom.
i have one problem and i need your help.
I have 1 HomeTroller Zee S2 with 2 arduinos.
1 Arduino (Uno) have 4 x DS18B20. (5-6 m cable cat 5)
1 Arduino (Mega) have 1 x DS18B20.(with 8m cable cat 5)
With all the sensors have the Error.
I tried to connect DS18B20 with 1=GND, 2=OUT, 3="+" and 1 resistor 4,7K. After I change the resistor to 2,2K and 1K.
I tried to connect 1+3=GND and 2=OUT with 4,7K to "+" ( http://www.theengineeringprojects.co...0-arduino.html)
But .... nothing.
After same minuts the sensors is in Error (but not all the sensors in the same moments)
