ds18b20 causing power issues for uno? - Sensors - Arduino Forum

hello, it is the first time i am tinkering with ds18b20 temperature sensor. i wired it like this: but to my surprise as soon as i start arduino with sensor connected it immediately disconnects, power led flickers as if there was a problem with power. right after sensor disconnection, arduino continues function. anyone can please hint me what could be the problem? i expected this to be rather a simple task. br, jose
