| Dec 17, 2015 at 16:24 | comment | added | brtiberio | Some sources advise to not use with multiple devices ( openenergymonitor.org/emon/buildingblocks/…). However data sheet says it is possible as long a strong pullup is present. I would go with the normal power with 4.7k pullup. Be very carefull connecting vdd to correct PIN in sensor. It will burn in seconds if you reverse polarity. | |

| Dec 17, 2015 at 15:10 | comment | added | serge1peshcoff | Wow, switching the resistor to 620R worked. Guess I have a problem within my breadboard. | |
