Arch GPRS: Is it possible to use Grove Temp/hum sensor??

Hi again

I have placed a Grove light sensor, and a Grove Temp/Hum sensor in the jar, together with the Grove Shield. All works fine, when connected via USB. But as soon as it is battery powered, the Temp/Hum sensor is not giving any output....

Can anyone explain that??
