Strange Behavior on DS18B20 Temp sensor and Pull-up Resistor

Make sure every sensor has a decoupling capacitor between Vcc and ground. With a large breadboard setup I'd worry about wiring integrity - recheck every connection.

Thanks for help

I already lowered the resistance, and worked.
But in next projects will be a must have the decoupling capacitors.
